HNO二聚体蓝移氢键的理论研究
Theoretical study of hydrogen bond blue-shift in the HNO dimer
摘要
Abstract
Ab initio molecular orbital and density functional theory (DFT) in conjunction with different basis sets calculations were performed to study the N-H...O blue-shifted hydrogen bond in the HNO dimer. The geometric structures, vibrational frequencies and interaction energies were calculated by both standard and CP-corrected methods. The topological and NBO analysis were investigated the origin of N-H bond blue shift. From the NBO analysis, the decrease in the σ*(N-H) is due to the significant electron density redistribution effect. The electron density redistribution effect, rehybridizative effect and the structure re-organization are contributed to the large blue shift of the N-H stretching frequency.关键词
