| Abstract: | The photodissociation of C4H5N]+˙ ions generated by ionization of pyrrole (1), allyl cyanide (2), crotonitrile (3), cyclopropyl cyanide (4) and methacrylonitrile (5) has been studied using ion beam techniques. At least four different stable ion structures have been distinguished, which is in contrast to earlier CAD studies. In addition it has been shown that C2H3N]+˙ fragment ions formed by dissociative ionization of the same precursors have structures which are distinct from that of ionized acetonitrile. |
