Abstract
Chemiluminescence (CL) resulting from single collisions of the Group IIIa metals with F2 has been studied in a beam–gas arrangement. Computer simulation of the wavelength scans yields relative rates of formation of the various vibrational and spin–orbit states. Population inversions are observed in the vibrational distributions for excited electronic states. The vibrational distributions are consistent with previously reported values for the metal fluoride bond strengths. Absolute CL cross sections on the order of 0.02 Å2 for GaF and 0.05 Å2 for InF are measured. The results suggest that the energy release occurs early in the course of the reaction, and that at least one nonadiabatic process occurs with high efficiency.
