Measurements of the partial charge transfer cross-sections for doubly charged ions X 2+ + Y → Y + + X + are described for C 2+ , N 2+ , A 2+ in He, Ne, A, and the results are discussed in terms of divergence from near-àdiabatic conditions caused by the crossing of potential energy curves. The single endothermic case C 2+ in He behaves adiabatically; all the others, which are exothermic, show large cross-sections at low energies. In the case A 2+ in A there is a contribution from double charge transfer, which cannot be distinguished experimentally from partial charge transfer.

Double Ionisation

Double ionisation of the triatomic molecules presented in this chapter shows an added degree of complexity. Besides potentially having many more electrons, they have three vibrational degrees of freedom (three normal modes) instead of the single one in a diatomic molecule. For asymmetric and bent triatomic molecules multiple modes can be excited, so the spectral bands may be congested in all forms of electronic spectra, including double ionisation. Double photoionisation spectra of H2O, H2S, HCN, CO2, N2O, OCS, CS2, BrCN, ICN, HgCl2, NO2, and SO2 are presented with analysis to identify the electronic states of the doubly charged ions. The order of the molecules in this chapter is set first by the number of valence electrons, then by the molecular weight.
