โœฆ Synopsis

The =CHI and =CD2 stretching vibrational overtones of H&-CD2 have been studied up to V= 6 and V= 3, respectively. We report their interpretation in terms of a transition from normal to local modes, involving Fermi resonance with the C-C stretching and CHz scissoring vibrations. We discuss the alternative representation of the vibrational Hamiltonian matrix in local mode and normal mode basis functions. and conclude that the normal mode basis offers greater flexibility in representing small anharmonic couplings with other modes.

The concentration dependence of vibrational linewidths in isotopic mixtures has been utilized routinely to ascertain the role of resonant energy transfer on vibrational relaxation in liquids. In a Raman study of the vr modes in CHaCla/CDaCla solutions, it was found that the C-H stretching linewidth
