Abstract

It is demonstrated that the second band in the photoelectron spectrum Of C2D4 is subject to strong non-adiabatic effects, as was previously found for C2H4. The calculation yields a dense and irregular vibronic line structure, the line density exceeding that expected from the Franck-Condon principle by two orders of magnitude. The feasibility of extracting vibrational frequencies from peak spacings of the envelope of such complex bands is critically, examined.
