✦ Synopsis

We report the dissociation of doubly excited states of molecular hydrogen into an excited and a ground-state atom. After threephoton excitations to various vibrational levels in the B 'Z: state, one-and two-photon excitations result in doubly excited states with a (2~0,) core of both gerade and ungerade symmetry. For the first time, excitation of Q, states with all principal quantum numbers is observed. Dissociation of these states results in a complete Rydberg series of atomic fragments, which are photoionized. The energy of the photoelectrons is measured. The series is characterized by the lower states, which are energetically resolved up to n = 5, and the limit n-co of the series.

For some lower-lying excited states of NH3 and H20, ab initio SCF calculations indicate the presence of potential maxima in the paths leading to dissociation into NH2 +H and OH +H. The occurrence of these maxima is probably connected with changes in the highest occupied molecular orbital during diss
