β¦ Synopsis
The Hg-CH4 van der Waals complex has been studied in a supersonic jet expansion, in transitions correlated with the 6 'SO+6 "PI mercury transitions. Fluorescence excitation spectra and action spectra have been recorded to analyse the corresponding transitions X-A and X+B. Through isotopic substitution of methane with deuterated methane, the origin band is assigned, and the vibrations of the complex characterised in a simple quasidiatomic fashion as stretching and bending motions of methane with respect to mercury. These motions correspond to the radial and angular potentials of the complex. Emission spectra from selected stretch levels in the A and B states have confirmed the vibrational quantum assignment and provided a full determination of the radial ground-state potential.

Van der Waals complexes of the bichromophore spirobifluorene with argon, nitrogen, water, methanol, and acetonitrile were studied in a supersonic jet. The 1: 1 complexes have two origin transitions which are shifted to the red and to the blue of the bare bichromophore origin. These spectral shifts a
The first reported spectrum of the \(\mathrm{CO}-\mathrm{Xe}\) van der Waals complex has been studied in the 4.7\(\mu \mathrm{m}\) region of the \(\mathrm{CO}\) fundamental band using a long-path ( \(104 \mathrm{~m}\) ) low-temperature ( \(110 \mathrm{~K}\) ) static absorption cell and a high-resolu
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
We report analyses of the potential energy surfaces of five van der Waals complexes, Ar-NH3, ((CH3)2NH)2, propene-SO z, acetylene-N 2 and acetylene-CO described by a potential based upon distributed multipoles for the electrostatics and atom-atom Lennard-Jones terms for the dispersion-repulsion. In
