 Title: VIBRATIONAL CIRCULAR DICHROISM OF (R)-(+)-3-METHYLCYCLOPENTANONE Creators: Laux, Leo J.; Hansen, John C.; Moscowitz, Albert Issue Date: 1985 Publisher: Ohio State University Abstract: The vibrational circular dichroism (VCD) spectra of (R)-(+)-3-methylcyclopentanone and its $2,2,5,5-d_{4}$ derivative in $CCl_{4}$ solution have been measured in the C-H and C-D stretching regions. The deuterated species shows a large $(|R| \sim 70 \times 10^{-45} esu^{2} cm^{2})$ bisignate VCD spectrum in the C-D stretching region. Attempts to account for these data by coupling among only four erstwhile degenerate C-D stretching modes fails. The data are better accounted for by more complex descriptions of the nuclear motions and attendant electronic charge flows that involve additional moieties, e.g. the carbonyl group.
