LASER-INDUCED FLUORESCENCE STUDY OF I2 FROM (CH3I)N PHOTODISSOCIATION

Ground electronic state I2 is detected using laser-induced fluorescence following the one-photon excitation of small methyl iodide clusters at 248 nm. The internal energy of the I2 is quite low, less than 3.5 kJ mol-1. No emission from electronically excited I2 is observed. These results suggest that unusual photodissociation dynamics occur in methyl iodide clusters, perhaps with the dimer acting as a separate photochemical unit.
