Stretching Vibrations of C-Br in P-Dibromobenzene Nanoparticles

Abstract

Raman spectrums of nanoparticles of a p-dibromobenzene with size of 300 nanometers and 50 nanometers are measured. It is found that frequencies of lines of stretching vibrations of C-Br at reduction of the sizes of nanoparticles below 300 nanometers are incremented. It is related to magnification of parameters of the lattice and interaction reduction between molecules.
