Formation and Deactivation Processes in Electronic Transitions, Chemically Pumped Lasers.

Abstract

Research was performed on the rates of formation of excess populations of electronically excited small molecules, particularly in chemiluminescent metal + oxidant reactions, and characterization of the deactivation processes which tend to relax these excited states. Results were obtained in the following areas: (1) aluminum + ozone reaction; (2) lanthanum + oxidant reactions; (3) reactions of silanes and boranes with oxidants; (4) scandium and yttrium oxidant reactions; (5) titanium + oxidant reaction; (6) chemiluminescent reactions of the Group IIIB metals; (7) optical model for surface crossing; (8) Information-Theoretic analysis of deactivation rates; (9) Spectroscopy and deactivation of CN A+2Pi; (10) near-resonant electronic energy transfer; and (11) multiphoton CO2 laser vibrational heating of metastable electronic states.
