ИК спектр метил-B-D-глюкопиранозида и его интерпретация на основе построения структурно-динамической модели молекулы

Abstract

Методом функционала плотности (B3LYP) в базисах 6-31 G(d), 6-31+G (d, p) построены структурно-динамические модели молекулы метилЯ-D-глюкопиранозида: минимизированы энергии, рассчитаны структуры, дипольные моменты, поляризуемости, частоты нормальных колебаний в гармоническом приближении и распределение интенсивности в ИК спектре молекулы. Дана интерпретация ИК спектра метилЯ-D-глюкопиранозида, измеренного в диапазоне 400-3700 см-1 при комнатной температуре. Обсуждены преимущества построенной модели в сравнении с моделью, основанной на использовании метода валентно-силового поля и валентно-оптической теории

Structural-dynamic models of the methyl-β-D-glucopyranoside molecule are constructed by density functional method in bases 6-31 G(d), 6-31+G (d, p). Energies, structures, dipole moments, polarizabilities, frequencies of normal modes in harmonic approximation and IR intensities have been calculated. Interpretation of IR absorption spectrum is presented in range 400-3700 cm-1. Advantages of model, which was constructed, compared with model, which bases on using valence-force field method and valency-optical theory, are discussed
