Resumen:
The simultaneous evaluation of the PES and valence synchrotron photoionization studies complemented by
the results of quantum chemical calculations offers unusually detailed insights into the valence ionization
processes of small covalent molecules. Thus, methyl thiochloroformate, ClC(O)SCH3, has been investigated
by using results from both photoelectron spectroscopy (PES) and synchrotron radiation in the valence energy
range. In an additional series of experiments, total ion yield (TIY) and photoelectron-photoion coincidence
(PEPICO) spectra have been recorded. Furthermore, the relative yields for ionic fragments have been determined
as a function of the photon energy. Vibronic structure has been observed in the TIY spectrum recorded in the
synchrotron experiments. The photodissociation behavior of ClC(O)SCH3 can be divided into two welldefined
energy regions.3, has been investigated
