CONTINUOUS-WAVE SUPERSONIC JET DIODE-LASER SPECTROSCOPY AND DYNAMICS OF AR-DCL - ROVIBRATIONAL ANALYSIS OF NU-1 AND NU-1 + NU-2(1) AND THE EFFECT OF CORIOLIS COUPLING IN THE SPECTRUM OF NU-1 + 2-NU-2(0)

The 1 fundamental and 1 + 21 intermolecular combination bands of the van der Waals dimer Ar-DCl have been observed using a sensitive tunable diode laser continuous-wave (cw) supersonic jet spectrometer. The experimental results are compared with frequency and intensity predictions based on variational calculations using the H6(3) potential of Hutson. A possible assignment of the 1 + 220 combination band is proposed on the basis of anomalous intensity predictions from these calculations. The calculations indicate that the R branch of the 1 + 220 combination band is much stronger than the P branch due to a strong Coriolis mixing of the 1 + 220 and 1 + 21 states. 1991 American Institute of Physics.
