The infrared spectrum of the C/sub 6/H/sub 6/-HF complex, formed by codeposition of Ar/benzene and Ar/hydrogen fluoride samples at 12 K, exhibits strong nu/sub s/ (H-F stretching) and nu/sub 1/ (H-F librational) fundamentals at 3795 and 253 cm/sup -1/ and eight out-of-plane wagging fundamental and combination bands for the benzene submolecule in the complex. The positions of the nu/sub s/and nu/sub 1/ modes indicate a weaker complex than C/sub 2/H/sub 4/--HF, and the observation of one degenerate nu/sub 1/ mode with a nu/sub 1/(HF)/nu/sub 1/(DF) = 1.390 ratio that is characteristic of a harmonic vibration supports a C/sub 6nu/ equilibrium structure for the C/sub 6/H/sub 6/ complex, in accordance with microwave studies. 23 references, 3 figures, 3 tables.
