【 摘 要 】

Fragmentation of complex molecules is studied linking the fragment-ions to the primary vacancies produced in their molecular orbitals. It is observed that a model based in such association describes well rather complex molecules. Deviations from this model are clear indications that inner valence-shells and double ionization plays a key role in the production of some fragments.
