Paper Abstract

Rate constants for collisional transfer between highly excited levels of I2(X) have been measured. A single vibration-rotation state (v' equals 42, J' equals 17) was populated by stimulated emission pumping. The prepared level, and collisionally populated levels, were detected by laser excitation of the D-X system. Relaxation kinetics were determined by variation of the delay between the dump and probe laser pulses. Collisions with He, Ar, I2, and O2 were investigated. Rotational energy transfer rate constants were measured for all collision partners. Vibrational energy transfer ((Delta) v equals 1) was observed for He, and O2, but this process was immeasurably slow for Ar and I2.
