The authors present the first simultaneous studies of fragment ion production and electron emission of a molecule following deep core-level excitation. Using synchrotron radiation they tune into various absorption resonances and correlate certain electron-hole states in the decay of the x-ray excitation with the appearance of specific ionic fragments. For N/sub 2/ specifically they observe a 1:1 correspondence between single valence hole states and undissociated N/sub 2//sup +/ after N 1s..--> pi..( excitation and relate the production of N/sup + +/ ions to the generation of holes in the 2sigma/sub u/ orbital.
