Far-Wing Absorption Profiles of a Reactive Collision: Mg +H2

Abstract

We report on preliminary studies of the far-wing absorption of laser light into the Mg${\mathrm{H}}_2$ reactive collision complex. We have measured the far-wing absorption profile leading both to the nonreactive channel (${\mathrm{Mg}}^{*}$ formation) and into a specific vibrational-rotational level of the reactive channel [MgH ($v^{\prime \prime }=0\mathrm{}$, $J^{\prime \prime }=23\mathrm{}$) formation].
