Abstract
Besides two strong and resonances in the 398- to 400-eV energy range, N 1 near edge x-ray absorption fine structure spectra of acrylonitrile molecules have a less intense 401- to 403-eV doublet. The two components correspond to the N 1 and N 1 transitions, where is a diffuse state with strong Rydberg character. The vibrational analysis shows that in the excited state, two low-energy -- normal modes are strongly excited. The excitation triggers a set of - vibrations, in particular, two C=C–CN bendings of the molecule.
