    Description / Table of Contents: The He(I) Photoelectron Spectra of (CH3)2PSCH3, (CH3)2AsSCH3, (CH3)2AsSeCH3 and (CH3)2PSeCH31)The He(I) photoelectron (PE) spectra of (CH3)2PSCH3 (1), (CH3)2AsSCH3 (2), (CH3)2AsSeCH3 (3) and (CH3)2PSeCH3 (4) have been recorded. The assignment of the first five bands is based on a comparison with the PE spectra of (CH3)3X, (CH3)2XX(CH3)2 (X = P, As) as well as of (CH3)2 and CH3YYCH3 (Y = S, Se). Additionally the measured ionization potentials have been compared with calculated orbital energies (CNDO, INDO, MNDO). The first two bands of the PE spectra of 1-4 are due to ionization events from linear combinations of the lone electron pairs.
    Notes: Die He(I)-Photoelektronen (PE)-Spektren von (CH3)2PSCH3 (1), (CH3)2AsSCH3 (2), (CH3)2AsSeCH3 (3) und (CH3)2PsSeCH3 (4) wurden gemessen. Die Zuordnung der ersten fünf Banden erfolgte durch Vergleich mit den PE-Spektren der Verbindungen (CH3)3X, (CH3)2XX(CH3)2 (X = P, As), sowie (CH3)2Y und CH3YYCH3 (Y = S, Se). Außerdem wurden die gemessenen Ionisationspotentiale mit berechneten Orbitalenergien (CNDO, INDO, MNDO) verglichen. Die ersten beiden Banden in den PE-Spektren von 1-4 können Ionisierungen zugeordnet werden, bei denen das Elektron aus Linearkombinationen der einsamen Elektronenpaare stammt.
