摘要:
The spectrum of the weakly-bound van der Waals complex Ar-CO has been observed for the first time in the region of the CO vibrational overtone, using a long-path (180 m) low-temperature (64 K) absorption cell and a Fourier transform infrared spectrometer. The appearance of the spectrum was very similar to that studied previously in thevco= 1 ← 0 region. However, it was very much weaker, so a detailed analysis was only possible for the relatively uncongestedK= 1 ← 0 and 0 ← 1 subbands. The parameters determined here for these sub-bands should help to constrain the C-O bond length dependence of the Ar-CO intermolecular potential in future theoretical models.
