Abstract : Techniques of optical spectroscopy have been used to study collisions between atoms, molecules and ions, and to obtain information on molecular constants and interactions in condensed gases. Light emission from approximately two dozen ion-molecule reactions has been measured in a molecular beam apparatus using low energy N2 and Ar ions. NO2 fluorescence excited by Ar and Kr ion lasers, and I2 fluorescence excited by a 5682 A Kr ion laser have been measured and interpreted. A low temperature apparatus has been used for attempted stabilization of metastable O2, for studying matrix isolation spectra of the transition metals; and for obtaining Mossbauer spectra of Co57 isolated in solid argon. Theoretical and experimental studies of the O4 molecule have been made. Additional information on the mechanisms of formation and destruction of ground state CN in active nitrogen flames has been obtained. Double resonance experiments with electronically excited CN has given more precise data on hyperfine levels and increased knowledge of collision processes in CN. (Author)
