Raman Spectroscopic Studies of CH₃– and CD₃-(4-<i>Tert</i>-butylpyridine)- bis(dimethylglyoximato)cobalt (III) Complexes: Reassignment of the Methyl-Cobalt Stretching Vibration

Abstract

Abstract By comparing the Raman spectra of the methyl-d0- and methyl-d3-(4-tert-butylpyridine)cobaloxime1 complexes, a number of bands were observed to shift due to the isotope effect. Bands appearing at 2900 cm−1 In the spectrum of the lighter molecule and at 2109 cm−1 in the spectrum of the C-deuterated species are assigned respectively to the axial methyl C-H and C-D symmetric stretches; the bands at 1172 and
