В приближении B3LYP/6-311G(d,p) рассчитаны оптимальная структура и колебательные (КР и ИК) спектры ТФМ. На основании визуализации колебаний теоретические моды и соответствующие им полосы экспериментального спектра КР отнесены к валентным и деформационным колебаниям определенных связей в молекуле ТФМ. Большинство полос, в частности наиболее интенсивные полосы в спектре КР ТФМ, обусловлены колебаниями в монозамещенных бензольных кольцах. Часть теоретических мод и соответствующих им экспериментальных полос отнесена к бензольным модам в нотации Вильсона. </p></abstract><trans-abstract xml:lang="en"><p>The Raman spectrum of polycrystalline triphenylmethane (TPhM) is recorded at room temperature in the range 4000-400 cm- 1  . The optimal structure and the vibrational spectra (Raman and IR) of TFM have been calculated in the B3LYP/6-311G (d, p) approximation. On the basis of visualization of vibrations, the theoretical modes and the corresponding experimental bands of the Raman spectrum are assigned to the valence and deformation vibrations of certain bonds in the TFM molecule. Most bands and, in particular, the most intense bands in the Raman spectra of TFM are due to vibrations in monosubstituted benzene rings. Some of the theoretical modes and the corresponding experimental bands are assigned to benzene modes in Wilson notation. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>трифенилметан</kwd><kwd>спектр комбинационного рассеяния</kwd><kwd>теория функционала плотности</kwd><kwd>triphenylmethane</kwd><kwd>Raman spectrum</kwd><kwd>density functional theory</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">N.
