Rotational Energy Transfer in Metastable States of Heteronuclear Molecules

Abstract

The objective of this program was to measure and interpret state-to-state R-T transfer rate coefficients for selected interhalogen molecules. Spectrally resolved CW laser-induced fluorescence was the experimental method used. A CW dye laser excites pure quantum states. The resolved fluorescence of the laser-excited level and the collisionally populated J' levels are analyzed. We have determined nearly 1000 state-to-state rate coefficients for R-T transfer in IF(B). Collision partners include He, Ne, Ar, Kr, Xe, N2, and CF4. Rate coefficients have also been determined for several initially excited J': 13, 27, 35 and 72. We have also investigated R-T transfer during vibrationally inelastic collisions for both I2 and IF. In addition, we have measured R-T rate coefficients in ICl(B). (jes)
