Correlations between the initial momenta of fragments from atomisation of ICN*+ and related molecules are examined by the photoelectron-photoion-photoion coincidence technique. The shapes of peaks in the spectra show that some fragmentation reactions are stepwise but faster than rotation of the intermediates; lifetimes in the subpicosecond range are estimated. Deviations of the peak shapes from predictions based on slow stepwise reaction are attributed both to reaction within the Coulomb repulsion zone and to energy release in decay of aligned intermediates. Suppression of rotation in intermediate ions by the strong Coulomb field is important in interpretation of the mechanisms.

SCF-energy partitioning for three ternary intermolecular complexes, (HF)3, Li\*(OH2)2 and F-(H2 0)2, has been performed in order to obtain more information on the nature of the non-additivities in the energies of complexes. It is found that polarization forces dominate the three-body energies in the
