High-resolution infrared predkociation spectra have been measured for dilute mixtures of CO2 and N1O in helium. Rotationalfme structure is clearly resolved for both (C02)2 and (N20)2, the linewidths being instrument-limited. This establishes that predissoaation lirehmes are longer than approGnately

The intermolecular potential surface was constructed for the carbon dioxide dimer for use in molecular simulations of the fluid state, including the super-critical region. During this procedure, peculiar potential curves were found for several specific configurations. There exist one maximum at the
