The gas-kinetic radius (r) and van der Waals coefficient (b) are two usable quantities for characterizing the motion of any molecules in the gas phase. In this article, comprehensive calculations of r and b of various environmentally sensitive molecules like SF6, NF3, GeF4, Si2H6 and Cl2O are reported. In the present study, an analytical approach for calculations of r and b was used from the electron impact cross-sections data of these molecules. In general, the reported values of r and b shows good agreement with the previous theories and experiments.

Photoelectron Angular Distributions

We use multiple scattering photoelectron diffraction (MSPD) theory to calculate the angular patterns of electrons photoemitted from the K-shell of CO and N 2 gas-phase oriented molecules, as recently measured by several groups. For low (E < 50 eV ) kinetic energies of the photoemitted electron, the electron scattering cannot be adequately represented by spherically symmetric potentials. We thus include nonspherical scattering potentials in our formalism through nondiagonal scattering matrices. We show that intramolecular scattering and interference are responsible for the experimentally measured patterns. This MSPD approach represents a more accurate and versatile method for dealing with such angular distributions as compared to prior calculations of these effects.
