Selective Photoionization and Photodissociation of Molecules Following Inner Shell Excitation

摘要

A review of the selective photoionization and photodissociation of molecules following inner shell excitation is presented. The localized character of the excitation around the absorbing atom shows that the electronic deexcitation and dissociation channels are specific. The recent experimental results obtained with synchrotron radiation by photoelectronic spectroscopy and mass spectrometry are examined: - competition between autoionization and dissociation in neutral fragments; - selective pathway of multiionization and selectivity of absorbing sites of the fragmentation channel of the residual ions.
