Download or read book Theoretical Prediction of Shape-resonance-enhanced Nuclear Motion Effects in Molecular Photionization written by and published by . This book was released on 1979 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shape resonances in molecular photoionization are predicted to induce strong non-Franck-Condon effects over a spectral range several times broader than the resonance half-width. This is manifested by large deviations from Franck-Condon vibrational intensity distributions and strong dependence of photoelectron angular distributions on the vibrational state of the residual ion. These effects are illustrated for the 3?g photoionization channel of N2 in Figures 1 and 2 using the multiple-scattering model and the adiabatic nuclei approximation.
