Abstract
We have observed excitation of the low frequency bending mode in Ar-HC1 using intracavity molecular beam laser-stark spectroscopy. An optically pumped far-infrared laser oscillating on a transition in $^{13}CH_{3}OD$ near $33.9 cm^{-1}$ was used to observe several laser-stark resonances in this molecule. Double resonance experiments show these to be transitions to the first excited $\pi$ bending state of the complex. In addition, radio frequency electric resonance has allowed the precise characterization of this state giving the following spectroscopic constants: We discuss the molecular structure in terms of these constants and make comparisons with Ar-HC1 potential energy surfaces.
