Abstract
The production of electronically excited iodine atoms is observed by time-resolved atomic absorption spectroscopy following the dissociation of molecular iodine excited by a tunable dye laser to the state above and below the thermochemical dissociation limit. The quantum efficiency is independent of excitation wavelength above the dissociation limit. Substantial yields of are found for excitation as much as below the dissociation limit.
