Investigation of the electronic structure of 2-(acetylamino)prop-2-enoic acid (N-acetyldehydroalanine) by HeI and HeII photoelectron spectroscopy

Abstract

He^I and He^II excited photoelectron spectra of N-acetyldehydroalanine (2-acetylaminoprop-2-enoic acid) are presented and discussed. Assignments are proposed by comparison with acetamide and acrylic acid and by analysis of the relative band intensities in the two spectra. The major perturbation with respect to the reference molecules arises from the interaction between the acetamido- and vinyl groups.
