摘要: Abstract Correlations between the initial momenta of fragments from atomisation ICN2+ and related molecules are examined by photoelectron—photoion—photoion coincidence technique. The shapes peaks in spectra show that some fragmentation reactions stepwise but faster than rotation intermediates; lifetimes subpicosecond range estimated. Deviations peak predictions based on slow reaction attributed both to within Coulomb repulsion zone energy release decay aligned intermediates. Suppression intermediate ions strong field is important interpretation mechanisms.
