title: Interatomic potentials of cadmium-argon B1(3sigma+) and X0+(1sigma+) states based on near-dissociation expansion and 'hot' bands observed in the B1 <-- X0+ excitation spectrum.
abstract: B1(3sigma+) <-- X0+(1sigma+) excitation spectrum of the cadmium-argon van der Waals molecule has been recorded in the experiment of a continuous supersonic molecular beam crossed with a pulsed dye laser beam. The B1-state dissociation energy was directly observed and a long-range behavior of the B1-state intermolecular potential was derived using a near-dissociation expansion procedure of LeRoy and Bernstein. A first-time direct determination of the X0+ ground state characteristics based on 'hot' bands observed is presented as well. The new result is compared with other experimental and theoretical reports available in the literature.
