Abstract
The internal rotation of the methyl group in toluene and nitromethane and the ring-puckering motion of cyclopentene have been studied by analysing the infrared and Raman spectra of the ν(CH) or ν(CD) stretching vibrations of the CH or CD oscillators isolated in selectively deuterated molecules. The interpretation of the spectra is supported by a general formalism of anharmonic coupling between the high-frequency and low-frequency modes. The latter is described in quantum mechanics in the gas and solid state but takes a stochastic character in the liquid state.
