The Raman spectrum of the ν 3 mode of allene has been studied as a function of temperature throughout the temperature range of the liquid. Analysis of the spectral band shape shows that the vibrational dephasing is a fast‐modulation process. Evidence is presented for a vibrational‐rotational coupling involving the tumbling reorientation of the molecule. Dilution studies in GeH 4 indicated significant resonant vibrational energy transfer.
