Popis: We report 2 + 1 resonantly enhanced multiphoton ionization spectra of HCl between 82000 and 89000 cm −1 two-photon energy with mass resolution of the ions. We see significant production of atomic products subsequently ionized when the two-photonresonant state has a long bond length but we see only HCl + when the resonant state is of Rydberg origin (and hence has a short bond length). The state at 82780 cm −1 , assigned as the E 1 Σ + (ν = 0) state, exhibits the production of atoms that is characteristic of a state with a long bond length, evidence that this state should be incorporated into the double-minimum B 1 Σ + state.
