气相中O3与HSO自由基间的氢键复合物
Hydrogen-Bonded Complex between Ozone and Thioperoxy Radical in Gas-Phase
摘要
Abstract
B3LYP/6-311++G** and MP2/6-311++G** calculations were used to analyze the interaction between thioperoxy radical (HSO) and ozone (O3) in gas-phase, which are of interest in atmospheric chemistry. The results showed that there were three equilibrium geometries (complexes Ⅰ,Ⅱ, and Ⅲ) at the B3LYP/6-311++G** level, but only one stable configuration (complexes Ⅱ) at MP2/6-311++G** level. And all the equilibrium geometries were confirmed to be stable states by analytical frequency computations. Complexes Ⅰ and Ⅲ use the 1H atom of HSO as proton donor and the terminal 40 atom of O3 as acceptor to form red shift hydrogen bond systems. However, complex Ⅱ uses the same proton donor and acceptor to form a blue shift hydrogen bond system. Interaction energies of the complexes corrected with basis set superposition error (BSSE) and zero point vibrational energy (ZPVE) lie in the range from -3.37 to -4.55 kJ·mol-1 at B3LYP/6-311++G** level. The natural bond orbital (NBO) and atoms in molecules (AIM) theories were also applied to explain the structures and the elecu'on density topology properties of the three hydrogen bond complexes.关键词
