Photoelektronenspektren von einigen Trihalogensilylphosphanen und -arsanen X3SiER2 (X =F, Cl; E = N, P, As; R = H, CH3) / Photoelectron Spectra of Some Trihalogensilyl Phosphines and Arsines X3SiER2 (X = F, Cl; E = N, P, As; R = H, CH3)

Abstract

The He (I) photoelectron spectra of the title compounds are described. The PE assignments are based on the comparison with the spectra of related compounds and on simple MO considerations (composite molecule–approach). The correlation between PE ionisation energies and molecular properties (e.g. SiP-(p→d)π-bonding) is discussed.
