| Abstract: | Anisotropic translational and rotational motion is observed in the ground-state hydroxyl radical generated by photolysis of trans-nitrous acid. The OH translational motion, determined from an analysis of Doppler line profiles, shows a sharply peaked velocity distribution with ≈46% of the total available energy (≈10300 cm?1) appearing in OH recoil. The OH internal state distribution, determined from the laser excitation spectrum, is vibrationauy and rotational cold and the two 2Π spin-orbit components are not in equilibrium. These results are compared with a simple impulse model for the fragmentation process. |
