[1] G.A Blake and R.E. Bumgarner. J. Chem. Phys. 91,7300(1989).Author Institution: Division of Geological and Planetary Sciences, 170-25, California Institue of TechnologyFar-infrared spectra of weakly bound complexes formed in a planar supersonic nozzle expansion of an Ar /H20/D20 mixture have been obtained using the CalTech far-infrared laser sideband spectrometer [1]. Weakly bound dimers of $Ar-HDO, Ar-D_{2}0$ and deuterated water dimers have been studied in the 500-700GHz range using the formic acid laser line at 584388MHz. Partial assignments of the spectra have been made. The spectroscopic parameters obtained from the data will be presented
