The image sketches representative vibrations and basic equations for a symmetric top molecule (benzene). Matteo Piccardo, Julien Bloino, and Vincenzo Barone discuss the topic on page 948 (DOI:10.1002/qua.24931) with the aim of presenting a comprehensive yet effective treatment of rotovibrational energies and thermodynamic functions by vibrational perturbation theory, including linear, symmetric, and asymmetric tops.
