The infrared spectrum of weakly-bound OCS-C6H6 is studied in the region of the ν1 fundamental band of OCS (˜2060 cm-1) using a tunable diode laser spectrometer to probe a pulsed supersonic jet expansion. A very simple band is observed, corresponding to a parallel transition of a symmetric top. It is shifted by -11.1 cm-1 with respect to the free OCS monomer. The resulting structure has OCS located along the benzene C6 symmetry axis in an S-bonded configuration with a center of mass separation of 4.42 Å, in good agreement with previous microwave spectra. The isotopomers OCS-13C12C5H6 and OC34S-C6H6 are also observed. Similar bands are observed for the OCS-C6H6-He and OCS-C6H6-Ne trimers, whose structure is obtained by adding an on-axis rare gas atom to the other side of the benzene. However, the analogous band for OCS-C6H6-Ar was not detected, raising the possibility that the stable form of this trimer may not have the same symmetrical structure.
