Quantitative Studies by Optical Spectroscopy of Energy Exchange in Simple Gases and Solids.

Spectroscopy in the visible and near ultraviolet regions has been used to investigate atomic and molecular collisions as well as photon initiated transitions in simple molecular collisions as well as photon initiated transitions in simple molecular systems. Low energy Ar and N2 ion beams have been used to give cross sections for twenty reactions. Na2 and BaO laser induced fluorescence has been used to determine molecular constants. Lattice frequencies for alkaloi sulphate and sodium chlorate crystals have been measured. Helium resonance radiation 58.4 nm has been used to dissassociate and excite simple molecules. The subsequent light emission has been measured and discussed. The effort of O and H atoms on the vibrational distribution of the N2 B triplet Pi state has been determined from observations made on the nitrogen afterglow. A theoretical investigation of dimerization in oxygen has been completed. Author
