โฆ Synopsis
The electron impact induced fragmentations of some unsubstituted and chlorine-substituted naphthalimides and bisnaphthalimides are discussed in detail with the aid of B/E and B'/E linked-scans for metastable ion analysis and collisional activation experiments. In the case of bisnaphthalimides the more important primary decomposition routes are related to cleavages of the alkyl chain.
