Paper Abstract

Predissociation and recombination kinetics of Iodine in both liquid (7°C) and fluid (19°C) Xenon have been studied by picosecond absorption spectroscopy. The results indicate lifetimes of ≈14 ps and ≈40 ps for predissociation and geminate recombination, respectively. Transient spectra of I2/Xe and I2/CC14 were also obtained, indicating the existence of a transient Iodine-solvent complex in CC14 that was not observed in Xenon. The kinetics of the prediss ciation of diazene compound and the spectroscopy of the resulting biradical have been studied by picosecond fluorescence spectroscopy. The data indicates diazene 2 has a lifetime of 38 ps and the singlet biradical 1S has a lifetime of approximately 280 ps. These results and the fluorescence spectrum are discussed in terms of known chemistry and theoretical calculations.
