    Description / Table of Contents: He(I) PE Spectra of (CH3)n(CF3)3-n for E = P, As, Sb and n = 0 - 3Based on the He(I) photoelectron (PE) spectra of (CH3)nE(CF3)3-n for E = P, As, Sb and n = 0 - 3 (1a-3d) the effect of CF3 groups on the first ionization energies has been investigated. It is found that the first ionization potential remains nearly constant on variation of E with constant but changes by about 0.7 - 1.2 eV by stepwise replacement of CH3 by CF3 substituents.
    Notes: Anhand der He(I)-Photoelektronen(PE)-Spektren der Verbindungen (CH3)nE(CF3)3-n für E = P, As und Sb und n = 0 - 3 (1a-3d) wird der Effekt von CF3-Gruppen auf die Ionisierungsenergien untersucht. Man findet praktisch keine Änderung der ersten Ionisierungsenergie, wenn E bei konstantem n variiert wird; dagegen resultiert bei schrittweisem Ersatz von CH3- durch CF3-Gruppen eine Erhöhung der Ionisierungsenergie um jeweils 0.7 - 1.2 eV.
