THE EXPERIMENTAL-DETERMINATION OF VIBRATIONAL TRANSITION MOMENTS FOR N2-HF AND OC-HF

Rovibrational transitions of OC-HF and N2-HF have been measured using vibrational predissociation spectroscopy in a molecular beam apparatus with a color-center laser. Analysis of the laser fluence dependence i n the saturation limit yields vibrational transition moments of 0.139 (6) and 0.091 (5) D for the HF subunit in OC-HF and N2-HF, respectivel y. These values are compared with other molecular properties associate d with the two binary complexes to characterize the role of the hydrog en bond.
