The sub-Doppler fluorescence imaging method has been developed to determine velocity distribution, angular distribution, and vector correlation of state-selected photofragments. Using this new method, photodissociation dynamics can be studied directly in the center-of-mass frame, even with an uncollimated molecular beam. We have performed the experiment of photodissociation of ICN at 308 nm to demonstrate that recoil velocities of photofragments can be obtained without collimating the parent beam. The forward- and backward-scattered CN(X 2S+) photofragments are imaged simultaneously for the first time. The recoil velocities of the CN photofragments are measured and the bond dissociation energy D00(I–CN) is determined to be 26960 ± 120 cm-1, in agreement with the literature values reported recently.
