Symmetry Breaking in the Lowest-Lying Excited-State of CCl: Valence Shell Spectroscopy in the 5.0-10.8 eV Photon Energy Range.

We report absolute high-resolution vacuum ultraviolet (VUV) photoabsorption cross-sections of carbon tetrachloride (CCl) in the photon energy range 5.0-10.8 eV (248-115 nm).

Low-Energy Electron and Positron Scattering by -Difluorobenzene.

The Schwinger multichannel method is employed in calculations of the elastic integral and differential cross sections for collisions of low-energy electrons and positrons with -difluorobenzene (1,4-CHF). The present calculations involving electron scattering have been performed using both static-exchange and static-exchange plus polarization levels of approximation. Our results indicate the presence of three resonances of π*-character in the low-energy region and a fourth resonance, of σ*-character, at higher energy levels.

Electronic State Spectroscopy of Nitromethane and Nitroethane.

High-resolution photoabsorption cross-sections in the 3.7-10.8 eV energy range are reinvestigated for nitromethane (CHNO), while for nitroethane (CHNO), they are reported for the first time.
