Resonance ion dissociation (RID) spectra are reported for cations of naphthalene and 2-methylnaphthalene cooled in a supersonic beam. Discrete vibronic resonances were observed in the ultraviolet region of both ions. A discrete red system was also observed for 2-methylnaphthalene that is subject to strong degenerate vibronic interaction with an underlying quasicontinuum associated with a lower energy electronic transition. This leads to effective power broadening of the RID spectra at moderately low laser intensities. The red two-photon dissociation process of 2-methylnaphthalene was successfully modeled by classical rate equations applied to a four level system, consisting of a ground state, the directly excited state, a lower energy excited state, and a final dissociative state.
