| Abstract: | The mass spectrometric dissociation feature of 2, 5-bis(4-hydrobenzylidene)cyclopentanonewas studied by means of tandem mass spectrometric techniques including both collision-induced dissociation and linked scan. It provides an evidence for the existence of a doubly charged ion of m/z 146. Furthermore, the collision-induced fragmentations of the doubly charged ion have been discussed. |
