摘　　要：应用串联质谱的碰撞诱导解离和联动扫描技术，研究了２，５－双（４－羟基苯亚甲基）环戊酮的质谱解离特征，提供了双电荷离子存在的实验证据。进一步对双电荷离子（ｍ／ｚ１４６）的碰撞诱导解离碎裂进行了讨论。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.
