Abstract
Recent high resolution infrared spectra recorded on a difference frequency and Pb-salt diode laser spectrometers have been obtained for $H_{2}HCl$ and $H_{2}DCl$ complexes, respectively. Analyses of these systems are used to characterize the internal rotor motion of the $H_{2}$ and the intermolecular potential which orients the subunits into a T-shaped asymmetric top complex. The spectra provide an opportunity to study any preferential orientation of DCl systems versus their HCl analogs. Such a differential intermolecular orientation has been demonstrated both $theoretically^{1}$ and $experimentally^{2}$ for rare gas . H(D)Cl complexes. The vibrationally averaged geometries of $H_{2}HCl$ and $H_{2}DCl$ are of interest since these systems provide a means of investigating photo initiated chemical insertion reactions of $D + H_{2}$ and $H + D_{2}$
