ANALYSIS OF THE DEFORMATION VIBRATION FREQUENCIES OF CHLOROBENZENE MOLECULES USING RAMAN SPECTROSCOPY

Abstract

In this article, the vibrational spectra of chlorobenzene, a liquid aromatic hydrocarbon, were studied over a wide frequency range using Raman spectroscopy. The modes of vibration of atoms at different frequencies are determined from the information obtained from the spectra. The feasibility of using a semi-empirical method to calculate potential barriers for chlorobenzene is demonstrated. Analysis using quantum chemistry methods revealed that the low-frequency part of the vibrational spectra primarily consists of stretching vibrations of the molecules.
