TY - JOUR A1 - Wittel, Klaus A1 - Astrup, Eva Elisabeth A1 - Bock, Hans A1 - Graeffe, Gunnar A1 - Juslén, Heikki T1 - Photoelectron spectra and molecular properties, XLVIII. Carbonates and thiocarbonates T2 - Zeitschrift für Naturforschung, B N2 - Photoelectron (PE) spectra of ethylene and vinylene carbonates and thiocarbonates as well as of methylene trithiocarbonate and some open-chain derivatives are reported. The low energy bands, well separated in the unsaturated compounds, are assigned to lone pair and π type ionizations. The assignment is based on comparison of PE spectra, modified CNDO calculations, and sulfur Κβ emission spectra. The pronounced substituent effects due to which the first ionization potential varies from 8.4 eV to 11.1 eV are discussed.
