We have observed an infrared spectrum within the X 3Σ− state of DCl2+ using a fast-ion-beam/laser-beam spectrometer. Sza¯arski, K. Yokoyama, G. Gerber.

The insight gained from these position-sensitive experiments is illustrated by a discussion of the results of studies of the reaction of CF22+ with H2O and the reactions of N22+ with a variety of neutral species.

The use of isotopic substitution was a useful tool, in this study and showed the correlation of the, intensity of the above barrier resonances with their, proximity to the barrier. Where there is a, signi®cant overlap of the wavefunction of the ini-, tial neutral molecule and the ®nal-state wave-, function of the molecular dication in the well, region a narrow peak in the photodissociation, We have calculated the resonance structure that, is supported by the Bennett/McNab potentials for, calculate the absorption coecients for single, photon double ionisation from HCl (DCl). Electron-transfer reactions ), (Note that the often used integral form of the partition function has a systematic error that does not imporove as J increases.).

The degeneracy of rotational levels is$g_J=2J+1. The absolute position of the potential functions and simulated spectra have been shifted by the energies shown to bring the v  0 resonances into alignment.
