Two theoretical models for the interpretation of the existing data of CH-stretching overtones' vibrational circular dichroism data are presented. The first model is based on the quantum mechanical Van Vleck contact transformation theory and is applied to the full vibrational problem, the second is b

✦ Synopsis
The reassignment of the CH stretching vibration fundamentals of cyclohexane is made by combination of experimental--i.r, and Raman spectroscopy--and theoretical--ab initio calculation methods. The Raman active bands are determined experimentally by polarized measurements. The position and intensity of the i.r. active bands are obtained by deconvolution of the band envelopes of the vapour phase spectrum. The calculated frequencies and relative intensities are in very good agreement with the experimental values, thus confirming the feasibility of the reassignment.
