Increasing amounts of data have shown that shape resonances play an important role in molecular photoionization. These resonances can lead to significant deviations of the vibrational branching ratios from Franck-Condon predictions and to vibrational state dependence of the photoelectron asymmetry parameters. They are one-electron in nature and their properties are determined primarily by the molecular core potential. These features suggest that their role in photoionization should be studied using realistic molecular potentials and photoelectron continuum states. We will first discuss the relevant aspects of the method we have developed for studying the electronic Hartree-Fock continuum states needed in molecular photoionization. We will then present the results of applications of this approach to resonant photoionization in several molecules including N_2, CO, CO_2, C_2H_2, and C_2N_2. Our emphasis will be on a comparison of these results both with experimental data and other theoretical predictions.
