Photoabsorption in the Schumann-Runge Bands and Continuum of O2

Abstract

Extensive laboratory measurements of photoabsorption in the Schumann-Runge bands and continuum of molecular oxygen have been made using The University of Adelaide six-metre vacuum ultraviolet monochromator. These measurements have shown for the first time rotational dependence in the band oscillator strengths and have provided comprehensive information about linewidths which is essential to an understanding of predissociation in the band system. The technique used to extract these values from the experimental data will be outlined, together with the results.
