Abstract
A direct absorption microwave and millimeterwave spectrometer capable of observing the rotational transitions of weakly-bound complexes formed in a planar supersonic nozzle has been constructed. Both the technique for observing weakly-bound complexes and its initial application to Ar-HCN and (HCN)_2 are described. The Ar-HCN lines reported here show significant frequency discrepancies (up to −3187.2 MHz) from predictions using previously obtained constants with distortion treatments through sixth order in J, reflecting the strong angular-radial coupling and pervasive intermolecular vibrational state mixing in this complex.
