โฆ Synopsis
The ionization potentials and the vibrational structure in the photoelectron spectrum of the CS molecule are calculated using a Green's function approach. The inclusion of many-body corrections to Koopmans' theorem is necessary in order to obtain the correct ordering of the first two ionization potentials. In contrast to previous interpretations of the spectrum the third band has to be assigned to a shakeup line and the fourth to the 60 orbital. The calculated vibrational structure is in good agreement with experiment and corroborates this assignment.

The high resofution photoelectron spectrum of CS has been obtained. Ionization potrntkds are found nt 11.34 (Xk), 17.78 (A\*lB, 15.83 (Bzc) and 18.03 (C'X) eV, and a spin-orbit bT;plitting of 278 cm-' is observed on the second band.
A theoretical study of the carbon 2s region of the photoelectron spectrum of ethylene is reported. The calculations are much larger than those previously performed and are successful in qualitatively describing the spectrum.
