The electronic spectrum of carbon dioxide. Discrete and continuum photoabsorption oscillator strengths (6–203 eV)

Abstract

The recently developed high resolution dipole (e,e) method, which is free of Beer—Lambert law “line saturation” errors, has been used to determine absolute photoabsorption oscillator strengths for the discrete electronic excitation of carbon dioxide in the energy region 6–30 eV. Low resolution dipole (e,e) measurements (1 eV fwhm) have also been made in the equivalent photon energy range 8.5–203 eV. The absolute scale of the present measurements was obtained by TRK sum-rule normalization.
