AbstractTheEgvibration at 1268 cm−1of cyclohexane is investigated by Raman scattering near the phase transition at 186 K. Within an interval of 1.5 K below the phase transition this band is split into five components with changing intensities. The spectra confirm the existence of a metastable phase. From the site and factor group of the stable phase the assignment of the absorption band at 862 cm−1in the infrared spectrum is establis
