i3C NMR spectra of a few odd-member alkane dicarboxylic acids such as glutaric and pimelic acids have been studied across their phase transitions. The spectra provide clear evidence for the structural changes accompanying the transitions. In the case of malonic acid, the study establishes that the t
## Abstract The __E__~g~ vibration at 1268 cm^β1^ of 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 m
