✦ Synopsis

The nuclear motion problem of the van der Waals molecules Ar-Hz and Ar-Ds is solved variationally in a basis of coupled spherical harmonics and Morse-type oscillator functions. Near-and far-infrared spectra are computed ab initio from a symmetryadapted perturbation theory potential calculated earlier. The resulting transition energies are found to agree with experimental data with an error of the order of 0.1 cm-I. This confirms that the potential is accurate.

A rovibrational spectrum of the acetylene-argon van der Waals (vdW) complex, C,H,-Ar, has been measured in the 1.52, pm '2vc-n' overtone region by a time-resolved infrared-ultraviolet double resonance method. Infrared absorption by the vdW complex is recorded as a depletion of laser-induced rovibron
