摘要

本文研究了凝聚体系中粒子振动光谱的一些问题。理论研究的一个方面是研究单个粒子的振动特性,考虑到粒子周围凝聚体系的分子的纳米尺度。利用温度仪、凝聚体系极化算子的格林函数,区分了介质对杂质粒子的两种主要影响机制:溶剂化和波动。在这两种机制的框架内得到了计算单个粒子振动谱变化的理论结果。利用理论结果分析了N2O分子在甲醇、乙醇、丙酮和1,2-二氯乙烷等极性溶剂中的振动谱实验数据。

THEORETICAL ASPECTS OF VIBRATIONAL SPECTROSCOPY OF CONDENSED SYSTEMS WITH IMPURITY PARTICLES
Some problems of vibrational spectroscopy of particles in condensed systems are considered in this work. One of the aspects of theoretical research is the study of the vibrational properties of individual particles in view of the nano-dimension of the molecules of the condensed system surrounding the particle. Using the apparatus of temperature, Green functions of the operators of polarization of condensed systems, two main mechanisms of influence on impurity particles from the medium, solvation and fluctuation, are distinguished. Theoretical results are obtained within the framework of these two mechanisms for calculating changes in the vibrational spectrum of individual particles. The theoretical results are used to analyze the experimental data on the vibrational spectra of the N2O molecule in polar solvents: methanol, ethyl alcohol, acetone, and 1,2-dichloroethane.
