The full nonrelativistic quantum mechanical vibrational J=0 kinetic energy operator for a hexatomic molecule, (A,B)-C-D-(E,F), expressed in valence stretch, bend, and torsion internal coordinates is given explicitly. The derivation of the operator is

The many-body Schrodinger equation for the vibrational states of H2CO and several of its isotopomers is solved by the diffusion quantum Monte Carlo algorithm. We report exact simulations for the energies and selected properties of the ground state an

Microwave and infrared measurements have been made for the van der Waals complexes N2–CH3CCH and CO–CH3CCH, and their isotopomers. The infrared spectra are complicated by the effects of a slightly hindered internal rotation of the propyne unit. T

The infrared spectra of the linear van der Walls molecules C[sub 2]H[sub 2]-N[sub 2] and C[sub 2]H[sub 2]-CO have been measured in a nozzle-beam apparatus with a rotational temperature of about 1.5 K. The spectrum consists of transitions from a singl

Ion beams with energies in the range 1–2 keV are used to sputter neutral Zr atoms from a polycrystalline surface. Laser induced fluorescence detection is used to obtain angular distributions of sputtered neutrals as a function of ion impact directi

Laser-induced fluorescence spectra of Zr atoms sputtered by ion bombardment have been obtained for the (5)F degrees (1) ? (3)F(2) transition at 595.5 nm. The isotopic shift of (91)Zr is found to be -70 +/- 40 MHz relative to the (90)Zr peak. A discre

A simple dipole moment function for the water molecule, written in terms of symmetry coordinates, is described. The model is for use with potential energy surfaces for water, and is expected to be particularly valuable for applications involving simu

The diffusion Monte Carlo method is used to simulate vibrational states for HF and DF monomers and dimers. Ground state energies, dissociation energies, and vibrational motions are discussed on the basis of the simulations. Vibrational frequencies fo
