Co-condensation of dilute Ar/HF and Ar/H2O samples at 12 K produces a number of sharp new infrared absorptions.The major species, which exhibits a strong 3554.7 cm-1 band and two quartets beginning at 753.1 and 635.6 cm-1, is identified as H2O- - HF.Isotopic substitution in the base submolecule changes the splitting in the latter multiplets and provides evidence for inversion doubling of the H-F librational modes in the H2O- -HF complex.The reverse complex HF- -HOH, identified at 3915.5 cm-1, exhibits a stronger interaction when HOH is replaced by DOD.Two H-F stretching fundamentals, which show small D2O shifts, increased markedly on sample warming and are assigned to the 1:2 complex H2O- -HF- -HF with an open structure.
