We have studied the spectroscopic and dynamic properties of several autoionizing Rydberg states of molecular hydrogen which converge to the vibrationally excited [ital v][sup +]=1 state of the ion, in the presence of a static electric field. Using the techniques of multiphoton ionization and time-of-flight mass spectrometry, we are able to separately observe the yield of dissociation and ionization after excitation of resolved Stark components of the Rydberg states. The energies of the Stark components can be modeled accurately by an energy matrix diagonalization calculation, when rotational interactions between states converging to different ion rotational states are taken into account. The dynamics of the different states in the Stark manifolds can be partly explained by assuming that they are governing by [ital l] mixing of predominantly predissociative [ital s] and [ital d] states and a dominantly autoionizing [ital p] state.
