摘要：

Spectra of dimers and trimers containing C6D6 and He, Ne, Ar, or H-2 are observed in the region of the C6D6 nu(12) fundamental using a pulsed supersonic jet expansion and a tunable optical parametric oscillator laser source. These are the first reported infrared spectra of hydrogen - benzene complexes. Two bands coupled by anharmonic resonance are studied for each complex: the nu(12) fundamental itself (approximate to 2289 cm(-1)) and the nu(2) + nu(13) combination band (approximate to 2276 cm(-1)). Vibrational shifts for the trimers are found to be approximately twice those of the corresponding dimer. Effective intermolecular separations for (H-2)(1,2)C6D6 are about 3.46 angstrom, similar to those determined previously from electronic spectra of (H-2)(1,2)-C6H6 and also similar to (Ne)(1,2)-C6D6.
