Theoretical studies on the molecular dependence of the bond dissociation after the core excitations. CH3OCO(CH2)nCN, n=0, 1, 2

Approximate theoretical normal and resonant Auger spectra for a series of methyl cyanoesters were calculated. To study the reported molecular dependence of the fragmentation patterns after the core excitations, a new measure, bond dissociation factor, was introduced. The siteselectivity and the state-specificity for a series of methyl cyanoesters are qualitatively explained.
