✦ Synopsis

Rotational coherence spectroscopy has been used to measure rotational constants for four isotopomers of the aromatlc-aromatic dimer petylene-benzene. Possibilities for the vibrationally averaged dimer geometry have been deduced from the measured values. In the geometries the benzene moiety is close to centrally bound to the perylene and such that its ring plane is parallel or nearly parallel to the plane of the perylene. The geometries are discussed in terms of both the intermolecular forces between the spccics and the structural results for other aromatic dimcrs.

The dissociation energy of the complex C6H6'H20 was determined by the threshold difference method. These complexes were produced in molecular beams via the expansion of a mixture of helium, and benzene and water vapors in the ratio of 96: 3: 1. The method requires the ionization potential of C6H 6
