The vibrational spectra of methyl substituted xylene molecules were studied in a wide frequency range by the method of Raman scattering of light. From the obtained data on the low-frequency spectra, the manifestation of the rotational oscillations of individual atoms of the groups was established. The possibility of using a semi-empirical method for calculating the potential barriers of methyl groups in methyl substituted xylenes is shown.
