“…The rovibronic term values extracted from our photoelectron spectra of thẽ A + Π(060), Σ(070) and Π(080) are in good agreement with the term values determined in the analysis of theÃ + -X + band system [1,3,10]. They are also in good agreement with the term values calculated ab initio by Brommer et al [18] who, however, optimized their ab initio potential to best reproduce the available experimental data.…”

The photoelectron spectrum of water has been recorded in the vicinity of theÃ + ←X transition between 112 000 and 116 000 cm −1 (13.89-14.38 eV). The high-resolution allowed the observation of the rotational structure of several bands. Rotational assignments of the transitions involving the Π(080), Σ(070) and Π(060) vibronic states of theÃ + electronic state are deduced from previous studies of theÃ + −X + band system of H 2 O + (Lew, Can. J. Phys. 54, 2028Phys. 54, (1976 and Huet et al. J. Chem. Phys. 107, 5645 (1997)) and photoionization selection rules. The transition to the Σ(030) vibronic state is tentatively assigned.

“…Below the first dissociation limit, the structure of H 2 O + is characterized by three bound states. The electronic ground state has C 2v symmetry similar to neutral water, with an equilibrium angle ∠HOH = 110.46 • and a bond length of R O−H = 0.9988Å [23,24]. Having C 2v symmetry, the ion is characterized by three normal vibrational modes, i.e., a symmetric stretch (ν 1 ), a symmetric bend (ν 2 ), and an asymmetric stretch (ν 3 ).…”

The decay of metastable states of the water radical cation H 2 O + has been observed in an experiment that combines photofragment momentum imaging and electrostatic ion-beam trapping in a crossed-beam geometry. Photoabsorption of 532-nm laser light from a fast beam of H 2 O + is observed to yield fragmentation into both OH 0 + H + and OH + + H 0 . Using coincident photofragment momentum imaging, the initial state of the observed photofragmentation is associated with low vibrational levels of the second excitedB 2 B 2 state of H 2 O + , dissociating via absorption onto a repulsive part of theÃ 2 A 1 state. Electrostatic ion trapping in the laser interaction region is used to follow the photofragment intensity as a function of time and to determine the lifetime of the metastable states to be τB 2 B 2 = 198 ± 11 μs.
