Continuous‐wave supersonic jet diode laser spectroscopy and dynamics of Ar–DCl: Rovibrational analysis of ν1 and ν1+ν12 and the effect of Coriolis coupling in the spectrum of ν1+2ν02 Academic Article uri icon


  • The ν1 fundamental and ν1 + ν21 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 ν1 + 2ν20 combination band is proposed on the basis of anomalous intensity predictions from these calculations. The calculations indicate that the R branch of the ν1 + 2ν20 combination band is much stronger than the P branch due to a strong Coriolis mixing of the ν1 + 2ν20 and ν1 + ν21 states. © 1991 American Institute of Physics.
