Abstract
The vibrational spectra of liquid aromatic hydrocarbons – bromobenzene, dioxane, toluene – are studied in a wide frequency range by means of Raman spectroscopy. The manifestation of torsional vibrations of individual groups of atoms is established from the obtained data on the low-frequency spectra. The possibility of using a semiempirical method for calculating the potential barriers of methyl and halide groups in benzene derivatives is shown.
