Molecular Orbital Interpretation of Xhyphen;Ray Emission Spectra: Simple Hydrocarbons and Carbon Oxides

摘要

The carbon xhyphen;ray emission spectra of CH4, C2H2, C2H4, C2H6, C3H8, C6H6, CO, and CO2obtained by Mattson and Ehlert are considered. The main parts of these spectra are shown to relate to the same ionized states as are observable by photoelectron spectroscopy, and generally may be interpreted with the help of molecular orbital theory. A simplified calculation of relative xhyphen;ray intensities based on extended Huuml;ckel wavefunctions gives good results for the compounds studied. Remaining structures on the highhyphen;energy side of the spectra are attributed to Wentzelndash;Druyvesteyn satellites.
