%X A comparison of the vibrational spectra of the N-methylpyridinium and N-methylpentadeuteropyridinium ions has shown that ring deuteration modifies the pattern of the ?substituent-sensitive? bands in the Raman spectrum considerably. This is expected if N-CMe stretching mixes largely with an aromatic CH in-plane bending rather than with purely skeletal vibrations. The effective symmetry of the ion is lower than C2v.
