Nonlinear Raman spectroscopy of ground-state intermolecular vibrations in benzene complexes
- Univ. of California, Los Angeles (United States)
We report the use of mass-selective, ionization-detected stimulated Raman spectroscopies in the study of ground-state intermolecular vibrational resonances in van der Waals complexes. Results are reported for one-to-one complexes of benzene isotopomers with Ar, Kr, and N[sub 2]. For these species a single Raman band is observed at 33.4, 35.2, and 37.2 cm[sup [minus]1], respectively. All of these bands exhibit rotational contours that are several cm[sup [minus]1] in width and without a dominant [sup 9]Q branch. They also exhibit polarization ratios indicative of nontotally symmetric vibrational transitions. They are shown to correlate with S[sub 1] vibrational intervals of slightly lower frequency. And, they exhibit red shifts of 2-3 cm[sup [minus]1] upon predeuteration of the benzene moiety. The bands are assigned as transitions involving the van der Waals bending mode in each of the species and are most likely fundamentals of the bend. 41 refs., 3 figs., 1 tab.
