The reaction of Hg(6 3P1)+H2, D2, and HD: Product rotational and vibrational distributions; isotope effects

Abstract
The initial vibrational and rotational state distributions of HgH and HgD products of Hg(6 3P1)+H2, D2, and HD have been determined. No isotope effect was observed for the vibrationless molecules or for HgH(v=1) but this effect appears for vibrationally excited HgD. The relative yields of the various reactions are reported for each vibrational level. In the reaction with HD, HgD is preferentially produced: [HgD]/[HgH]≂6.7.
