Vibrational circular dichroism (VCD) spectra are reported for (+), (-) and (-+) a-pinene, and (-) /3-pinene, isolated in argon matrices at ~18 K. These are the first observations of VCD of matrix-isolated molecules. Spectra are limited to the C-H stretching region (2800-3100 cm -1 ). In all cases, t

It is now established that the circular dichroism in vibrational transitions (v.c.d.) of chiral molecules is a measurable phenomenon'. In v.c.d. measurements (3n -6) vibrational transitions can be probed, whereas, in conventional cd. measurements in the visible region, only a few electronic transit
