Inner-shell photoionisation in molecules: the carbon monoxide case

Abstract

The inner-valence-shell photoionisation of CO has been studied by electron spectrometry using monochromatised synchrotron radiation in the region of 34 to 100 eV. The analysis of the experimental data and the quantitative comparison with theoretical calculations illustrate the important role electron correlation and shape resonances play in the explanation of the main features of these photoelectron spectra.
