Abstract : The electronic spectra and energy transfer pathways of matrix isolated Iodine monofluride and diatomic iodine have been investigated. Laser excitation of matrix isolated IF revealed the presence of three electronic states which had not been observed previously. The lowest energy state was identified as A(3)pi(2). Determination of the position and lifetime of this state has provided a means for assessing its role in the chemical excitation of the B state. The higher energy states have been tentatively assigned to a doubly excited electronic configuration. The I2 A yields X system was studied in Argon, Krypton, and Xenon matrices. Analyses of the emission spectra showed that previous vibrational assignments were in error. The A state lifetime was found to be 50 + or - 15 microseconds in all three matrix hosts. Continuous wave excitation and wavelength-resolved flourescence techniques were used to study the self-quenching and energy transfer kinetics of diatomic bromine (B).
