Shape in molecular photoionization are shown to induce strong coupling between vibrational and electronic motion over a spectral range several times broader than the resonances half-width of the resonances. This coupling is manifested by large deviations from Franck-Condon intensity distributions and strong dependence of photoelectron angular distributions on the vibrational state of the residual ion. The effects are illustrated for the 3sigma/sub g/ photoionization channel of N/sub 2/.
