β¦ Synopsis
Molecular octopole moments are rigorously calculated using two different semi,empirical wavefunctions. The resuits are compared with ab initio calculations and experimental data where available. IEHT wavefunctions are found to give a reasonable representation of multipole moments up to octopole.

## Ab initio calculations of binding energies with a transition operator method are performed. They are demonstrated to include relaxation, which is essential for the prediction of deep-hole chemical shifts.
In the aim of achieving a better understanding of the molecular mechanisms involved in the absorption continuum of the water-vapor rotational spectrum, various H 2 O-X mixtures are investigated in an atmospheric window in the mmw range. In the present study, the X mixing gas is methane. Absolute abs
