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
A suitable method to synthesize molecules like Sβ«Χ‘β¬Geβ«Χ‘β¬S, which cannot be obtained by heating of the well known solids, is provided by the matrix-isolation technique. In solid noble or other inert gases, GeS molecules react with S-atoms, which are produced photochemically from cocondensed COS. The
