The photodissociation and recombination dynamics of solution phase molecular iodine have been extensively studied both theoretically and experimentally. The simplicity of the reaction, I2→I+I→I2, along with iodine’s well understood spectroscopy [1],have resulted in numerous picosecond laser experiments [2–6] as well as molecular dynamics[5], generalized Langevi n[7] and other theoretical studies.[8–10] Despite these efforts, several fundamental questions have remained unanswered. For example, the rate of vibrational relaxation in the ground electronic state has not been directly determined. However, recent experimental [5] and theoretical [5,7,8] studies have suggested that vibrational relaxation may take ~100ps. Furthermore, recent rare gas matrix isolation studies by FLYNN[11] and theoretical studies by MILLER[9] have suggested that recombination into excited electronic states may be an important relaxation mechanism. The results presented here will further address these questions of electronic and vibrational relaxation.
