Double-resonance multiphoton ionization is used to probe unstudied Franck-Condon regions in transitions between excited electronic states in molecular hydrogen. The first resonance is selected for a long average internuclear distance, and absorptions of a second delayed laser pulse at energies near the second dissociation limit are detected as peaks in the delayed ionization spectra. New spectroscopic and photodynamic information on the highest excited bound vibrational levels of the B, B', and C electronic states is obtained.
