The IR spectrum of the C6H6-Ar cation is dominated by a Fermi resonance between the IR active nu(11) mode and two components of the combination mode of the lowest frequency modes nu(6) and nu(16). A stringent upper limit of 316 cm(-1) is found for the value of the dissociation limit D-0 of the neutral C6D6-Ar complex. (C) 1999 American Institute of Physics.
