  • Laser-induced Fluorescence Spectroscopy of NiCl in 12900–15000 cm
           −1
    • Authors: Cheng-bing Qin; Jian-zheng Zang, Qun Zhang Yang Chen
      First page: 631
      Abstract: Laser-induced fluorescence excitation spectra of jet-cooled NiCl molecules were recorded in the energy range of 12900–15000 cm −1 . Six vibronic bands with rotational structure have been observed and assigned to the [13.0] 2 Π 3/2 (ν′= 0–5)- X 2 Π 3/2 (ν″=0) transition progression. The relevant rotational constants, significant isotopic shifts, and (equilibrium) molecular parameters have been determined. In addition, the lifetimes of the observed bands have also been measured.

  • Linear and Nonlinear Optical Properties of Novel Multi-branched Oligomers
    • Authors: Li-jing Gong; Ying-hui Wang, Zhi-hui Kang, Tian-hao Huang, Ran Lu Han-zhuang Zhang
      First page: 636
      Abstract: We investigate the fluorene-vinylene unit dependent photo-physical properties of multi-branched truxene based oligomers (Tr-OFV n , n =1–4) employing steady-state absorption and emission spectroscopy, transient absorption spectroscopy, two-photon fluorescence, and z-scan technique. The results show that the increasing of fluorene-vinylene unit leads to a red-shift in the spectra of absorption and fluorescence, and shortens the excited state lifetime. Meanwhile, two-photon fluorescence efficiency and two-photon absorption cross section of truxene based oligomers gradually enhance in company with the extension of π-conjugated length. In addition, the values of two-photon absorption cross section modeled on the sum-over-state approach agree well with the experimental ones. The results indicate multi-branched truxene based oligomers bearing oligo(fluorene-vinylene) arms are promising organic materials for two-photon applications.

  • Density Functional Theory Study on Interaction between Catechin and
           Thymine
    • Authors: Wan-fei Cai; Yan Zheng, Lai-cai Li An-min Tian
      First page: 642
      Abstract: The interacting patterns and mechanism of the catechin and thymine have been investigated with the density functional theory Becke's three-parameter nonlocal exchange functional and the Lee, Yang, and Parr nonlocal correlation functional (B3LYP) method by 6−31+G * basis set. Thirteen stable structures for the catechin-thymine complexes have been found which form two hydrogen bonds at least. The vibrational frequencies are also studied at the same level to analyze these complexes. The results indicated that catechin interacted with thymine by three different hydrogen bonds as N—H···O, C—H···O, O—H···O and the complexes are mainly stabilized by the hydrogen bonding interactions. Theories of atoms in molecules and natural bond orbital have been adopted to investigate the hydrogen bonds involved in all systems. The interaction energies of all complexes have been corrected for basis set superposition error, which are from −18.15 kJ/mol to −32.99 kJ/mol. The results showed t...

  • Softening of C—H Symmetric Stretching Vibrational Modes for CH 2 and
           CH 3 Radicals Adsorbed on Cu n ( n =1–6) Clusters
    • Authors: Xi-hui Cheng; Da-jun Ding, Yong-gang Yu Ming-xing Jin
      First page: 649
      Abstract: The properties of C—H vibration softening for CH 2 and CH 3 radicals absorbed on Cu n ( n =1–6) clusters have been investigated, using the density functional theory with hybrid functional. The results indicate that the absorption of CH 2 on Cu clusters is stronger than the case of CH 3 . The vibrational frequencies of C—H bonding agree with the experimental results obtained for CH 2 and CH 3 absorbed on Cu(111). With the increase of cluster size, the softening (Einstein shift) of C—H vibrational modes become stronger.

  • Hydrogen-bonded Intramolecular Charge Transfer Excited State of
           Dimethylaminobenzophenone using Time Dependent Density Functional
           Theory
    • Authors: Yu-ling Chu; Zhong Yang, Zhe-feng Pan, Jing Liu, Yue-yi Han, Yong Ding Peng Song
      First page: 654
      Abstract: Density functional theory and time-dependent density-functional theory have been used to investigate the photophysical properties and relaxation dynamics of dimethylaminobenzophenone (DMABP) and its hydrogen-bonded DMABP-MeOH dimer. It is found that, in non-polar aprotic solvent, the transitions from S 0 to S 1 and S 2 states of DMABP have both n→π * and π→π * characters, with the locally excited feature mainly located on the C=O group and the partial CT one characterized by electron transfer mainly from the dimethylaminophenyl group to the C=O group. But when the intermolecular hydrogen bond C=O···H—O is formed, the highly polar intramolecular charge transfer character switches over to the first excited state of DMABP-MeOH dimer and the energy difference between the two low-lying electronically excited states increases. To gain insight into the relaxation dynamics of DMABP and DMABP-MeOH dimer in the excited state, the potential...

  • First Principles Study of Al-Li Intermetallic Compounds
    • Authors: Hai-li Yu; Xiao-hui Duan, Yong-jun Ma Min Zeng
      First page: 659
      Abstract: The structural properties, heats of formation, elastic properties, and electronic structures of four compositions of binary Al-Li intermetallics, Al 3 Li, AlLi, Al 2 Li 3 , and Al 4 Li 9 , are analyzed in detail by using density functional theory. The calculated formation heats indicate a strong chemical interaction between Al and Li for all the Al-Li intermetallics. In particular, in the Li-rich Al-Li compounds, the thermodynamic stability of intermetallics linearly decreases with increasing concentration of Li. According to the computational single crystal elastic constants, all the four Al-Li intermetallic compounds considered here are mechanically stable. The polycrystalline elastic modulus and Poisson's ratio have been deduced by using Voigt, Reuss, and Hill approximations, and the calculated ratios of bulk modulus to shear modulus indicate that the four compositions of binary Al-Li intermetallics are brittle materials. With the ...

  • Protonation Effect on One- and Two-photon Absorption Property of a Newly
           Synthesized Octupolar Chromophore
    • Authors: Hong-juan Ding; Jie Sun Chuan-kui Wang
      First page: 666
      Abstract: The protonation effects on one- and two-photon absorption properties of an octupolar molecule TA with 1,3,5-triazine core and pyrrole electron-donating end-groups have been studied at hybrid density functional theory level. A computational scheme is developed to simulate a proton attached to an atom. The numerical results show that large changes in both one- and two-photon absorption properties are observed when the compound is transformed from neutral to threefold protonated states. When the compound is protonated, more charge transfer states appear and the absorption band has a red-shift. Furthermore, the two-photon absorption cross-section is largely enhanced. The theoretical calculations demonstrate the protonation effect on promoting the intramolecular charge transfer strength. The results present qualitative agreement with the experimental observations. A two-photon absorption switch with the compound TA based on the protonation effect is proposed.

  • First Principles Study on Encapsulation of Alkali Metals into ZnO Nanocage
    • Authors: Mohammad T. Baei; Ali Ahmadi Peyghan Zargham Bagheri
      First page: 671
      Abstract: Encapsulation of alkali metals (Li, Na, K, and Rb) into Zn 12 O 12 nanocage has been investigated using density functional theory. Encapsulation of Li and Na atoms is found to be thermodynamically favorable at 298 K and 100 kPa, with negative Gibbs free energy change Δ G of about −130.12 and −68.43 kJ/mol, respectively. By increasing the size of encapsulated atom the process become less favorable so that in the cases of K and Rb encapsulations the Δ G values are positive. The results indicate that the LUMO, Fermi level, and specially HOMO of the cluster are shifted to higher energies so that the HOMO-LUMO gap of the cluster is significantly narrowed in all the cases. After encapsulation of the alkali metals the work function of cluster is decreased due to the shift of the Fermi level to higher energies. Therefore, the emitted electron current density from the Zn 12 O 12 cluster will be increased.

  • Theoretical Studies on Dehydrogenation Reactions in Mg 2 (BH 4 ) 2 (NH 2 )
           2 Compounds
    • Authors: Zheng Chen; Zhe-ning Chen, An-an Wu, Guo-tao Wu, Zhi-tao Xiong, Ping Chen Xin Xu
      First page: 676
      Abstract: Borohydrides have been recently hightlighted as prospective new materials due to their high gravimetric capacities for hydrogen storage. It is, therefore, important to understand the underlying dehydrogenation mechanisms for further development of these materials. We present a systematic theoretical investigation on the dehydrogenation mechanisms of the Mg 2 (BH 4 ) 2 (NH 2 ) 2 compounds. We found that dehydrogenation takes place most likely via the intermolecular process, which is favorable both kinetically and thermodynamically in comparison with that of the intramolecular process. The dehydrogenation of Mg 2 (BH 4 ) 2 (NH 2 ) 2 initially takes place via the direct combination of the hydridic H in BH 4 − and the protic H in NH 2 − , followed by the formation of Mg—H and subsequent ionic recombination of Mg—H δ− ··· H δ+ −N.

  • Local Structures and Chemical Properties of Deprotonated Arginine
    • Authors: Hong-bao Li; Zi-jing Lin Yi Luo
      First page: 681
      Abstract: The potential energy surface of gaseous deprotonated arginine has been systematically investigated by first principles calculations. At the B3LYP/6-31G(d) level, apart from the identification of several stable local structures, a new global minimum is located which is about 6.56 kJ/mol more stable than what has been reported. The deprotonated arginine molecule has two distinct forms with the deprotonation at the carboxylate group (COO − ). These two forms are bridged by a very high energy barrier and possess very different IR spectral profiles. Our calculated proton dissociation energy and gas-phase acidity of arginine molecule are found to be in good agreement with the corresponding experimental results. The predicted geometries, dipole moments, rotational constants, vertical ionization energies and IR spectra of low energy conformers will be useful for future experimental measurements.
