Stretching Vibrations of C-Br in P-Dibromobenzene Nanoparticles

TL;DR

This study investigates how reducing nanoparticle size affects the vibrational frequencies of C-Br bonds in p-dibromobenzene, revealing size-dependent shifts linked to lattice parameter changes and molecular interactions.

Contribution

It provides experimental evidence of size-dependent vibrational frequency shifts in p-dibromobenzene nanoparticles, highlighting the influence of nanoparticle size on molecular vibrations.

Findings

Vibrational frequencies of C-Br increase as nanoparticle size decreases below 300 nm.

Size reduction leads to lattice parameter magnification.

Molecular interaction reduction correlates with vibrational frequency shifts.

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.
