Determination of Vacancies Allocation in a Monocrystal of a P-Dichlorobenzene Using a Method of the Raman Spectroscopy

TL;DR

This paper uses Raman spectroscopy to analyze vacancy distribution in a p-dichlorobenzene monocrystal, providing a non-destructive method to identify structural defects.

Contribution

It introduces a novel application of Raman scattering to determine vacancy locations in a monocrystal, linking spectral lines to vacancy presence.

Findings

Certain spectral lines correlate with vacancy presence.

Vacancy distribution can be mapped using Raman intensity comparisons.

Method offers a new way to analyze crystal defects non-destructively.

Abstract

The method of Raman scattering is used to investigate the cross edge of a p-dichlorobenzene monocrystal, which was grown up by a Bridgmen method. Comparison of intensities of additional lines of a spectrum of the lattice oscillations of certain parts of an edge of a monocrystal with density of these fields has allowed to relate some lines to presence of vacancies in structure.
