Notes:
The temperature dependence of the Raman scattering from a single crystal of acetanilide (ACN-H) and fully deuterated acetanilide (ACN-D) in the low-frequency (phonon) and C=O stretching regions was studied. The observed normal behaviour of the frequency shift of the C=O stretching modes in ACN-D, raises questions concerning several theoretical models previously proposed to explain the peculiar behaviour with temperature of the A1g stretching modes observed in ACN-H. The forms of the low-frequency Raman spectra for ACN-H and ACN-D are very similar, except in the frequency range 70-120 cm-1, where an additional mode (denoted D′) is seen in the Raman spectrum of ACN-D. A strong temperature dependence of the frequency of this band is observed. The origin of this mode is still undecided.
