Complete quantum state distributions for HD (u= 1) and HD(u=2) are obtained by photolyzing HI at 266 nm m the presence of D2 and detecting the nascent HD product via (2+ 1) resonance-enhanced multiphoton ionization (REMPI). Calibration against an effusive oven source ( d 1800 K) yields any necessary

β¦ Synopsis
Recent independent experimental determinations. by Za.re and Valentini and their co-workers, of the HD product state distribution are consistent with a common set of surprkal parameters: h, = 2 and 0R in the range 3-5. Analysis of rhe computational results of Blais and Trublar su,, ~oests that a some\vhsr larger fraction of the avatible energy is channeled into rotation and that theorientatiofl of the emergent HD molecules is constrained.
