Abstract
We have measured the VCD spectra of a number of cyclic ketone derivatives. These data, together with previously reported VCD data for cyclohexanone derivatives, are analyzed on the basis of the charge flow $model.^{1}$ Such analysis suggests a revision of some of the earlier assignments made by Marcott $\frac{et}{3}$,$\frac{al}{4}$.$^{2}$ for the VCD bands observed for (+)-(3R)-methylcyclohexonone. Of additional interest, we have found differences in the VCD spectra of (I) and (II) which are interpretable in an analogous way to the sign differences previously observed and interpreted for the CD-stretching modes of (R)-(-)-neopentyl-1-d-chloride and (R)-(-)-neopentyl-1-d-$bromide.^{5,6}$ [FIGURE]
