Abstract:
HD molecules formed in v"=3 and v"=4 have been detected by laser spectroscopy when a cold (15 K) graphite surface is irradiated with H and D atoms. Population of the v"=3, J"=0-6 and v"=4, J"=0-6 levels has been detected and the average rotational temperatures of the nascent HD were determined. These results are compared with previous data collected for the formation of HD in v"=1 and 2 under similar conditions. This comparison indicates that the nascent HD flux increases with increasing vibrational quantum number for v"=1-4.
