Spectroscopic Studies of the Halogens.

Abstract

This report summarizes a range of work, both theoretical and experimental, involving the spectroscopy of the diatomic halogens in the gas phase. Included are 1) Analysis of absorption, fluorescence, and emission spectra -- both discrete and diffuse -- of Iodine Bromine, Chlorine, Iodine Chloride, Iodine Bromide, Iodine Fluoride, Bromine Chloride, and Bromine Fluoride; 2) The development of improved computational methods for evaluating diatomic partition functions, simulating spectra, computing centrifugal distortion constants, fitting spectral data to mixed polynomial and near-dissociation representations by the method of least squares, analyzing predissociation data, and calculating total radiative decay rates; 3) The determination of the transition moment function for the B-X transition in I2 from very high resolution measurements of absorption by single rotational lines, using a cw dye laser as source; and 4) Kinetics studies of the thermal dissociation of the A' state of I2 following preparation via excimer laser photolysis of I2 in Helium, Argon, Nitrogen, and Sulfur hexafluoride.
