Infrared double resonance spectroscopy has been carried out on the ..nu../sub 3/ reverse arrow 0 transition in SF/sub 6/. Both two- and three-level signals are observed. There is some indication of vibrational angular-momentum relaxation during the excitation pulse. Multiple infrared photon-induced dehydrohalogenation of vinyl chloride has been studied in detail. Excitation in either the ..nu../sub 7/ or ..nu../sub 10/ normal vibrations appears to be about equally effective in promoting the reaction. Multiple infrared photon excitation of B/sub 5/H/sub 9/ leads to production of B/sub 5/H/sub 11/ and B/sub 6/H/sub 10/ as well as molecular hydrogen and polymeric material. Intense chemiluminescence is also observed.
