Selectivity in fragmentation of N-methylacetamide
 |
The fragmentation pattern of the peptide model system, N-methylacetamide, after resonant K-shell excitation is investigated using ion time-of-flight spectroscopy. A tendency for site-specific fragmentation, in particular preferential peptide bond cleavage occurring upon resonant excitation of N1s electrons is observed. P. Salen et al. PCCP (2014)

The soft X-ray absorption spectrum of the allyl free radical
 |
HR XAS of the allyl free radical (CH2CHCH2)) was measured using a3D-ion-coincidence TOF mass spectrometer. The intense features in the spectrum could be assigned with the aid of ab initio simulation at the MCSCF level, required because of the multi-reference nature of the core-excited state wavefunctions of the open shell molecule. M. Alagia et al PCCP (2013)

Production of excited H at C1s edge of the methane molecule studied by VUV-photon-photion and metastable-fragment-photion coincidence experiments
 |
Core ionization of a molecule just above the 1s ionization potential leads to recapture processes where the photoelectron is pushed back to a high Rydberg orbital of the molecular ion. Upon dissociation highly excited neutral fragments can be produced together with ions.
