Abstract With a tunable laser we have selectively excited rovibrational levels in then=3 triplet gerade states of H2. These levels fluoresce to theb 3Σ u + state followed by dissociation. The released kinetic energy spectra of the fragments are measured with translational spectroscopy. These spectra reflect the structure of the product of the excited state vibrational wavefunction and the transition dipole moment. Applying a simple transformation, this product can be recovered as a function of internuclear distance. From the comparison between the experimental result and wavefunctions, calculated in diabatic potentials, we have extracted theR dependence of the transition dipole moments for theg 3Σ g + →b 3Σ u + andi 3∏ g →b 3Σ u + transitions. The spectra suggest that a diabatic description is more realistic for theg 3Σ g + levels than an adiabatic.
