Abstract

Inelastic incoherent neutron scattering (IINS) study of the lattice and low-frequency internal vibrations (libration of methyl groups and benzene ring deformations) of mesitylene molecules were carried out at various temperatures. In solid phase at ca. 20 K, the above enumerated vibrations are represented in form of well-separated peaks in the low-temperature IINS spectrum. The experimental data are compared with the results of quantum chemistry (QC) calculations.
