ABSOLUTE OPTICAL OSCILLATOR-STRENGTHS FOR DISCRETE AND CONTINUUM PHOTOABSORPTION OF CARBON-MONOXIDE (7-200 EV) AND TRANSITION MOMENTS FOR THE X1-SIGMA+-]A1-PI SYSTEM

Absolute optical oscillator strengths for the photoabsorption of carbon monoxide have been determined in the energy region 7-200 eV using low resolution dipole (e, e) spectroscopy and TRK sum-rule normalization. High resolution dipole (e, e) spectroscopy has been used to measure the absolute optical oscillator strengths for the photoabsorption of carbon monoxide in the valence shell discrete region from the first excitation threshold to 21 eV. Values of the absolute optical oscillator strengths for excitation of the vibrational levels of the A 1PI, C 1SIGMA+, B 1SIGMA+ and E 1PI excited electronic states are reported. The variation of transition moment with internuclear distance is investigated for the vibronic bands of the X 1SIGMA+–>A 1PI transition.
