摘要：

Besides two strong pi(*)(perpendicular to 1) and pi(parallel to)* resonances in the 398- to 400-eV energy range, N 1s 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 1s -> pi(*)(perpendicular to 2) and N 1s -> D parallel to* transitions, where D parallel to* is a diffuse state with strong Rydberg character. The vibrational analysis shows that in the D parallel to* excited state, two low- energy out-of -plane normal modes are strongly excited. The p(perpendicular to 2)* excitation triggers a set of in-plane vibrations, in particular, two C=C-C N bendings of the molecule.
