结果表明，1,4‐苯并二苯的苯基和苯并环丁基衍生物在低内能下裂解前发生了相互转化。通过动能释放测定和外观能测定，研究了两种主要的HCO和C6H5CO损失的机理。从这些实验中得出结论，碎片离子具有双苯并吡喃结构。
It is demonstrated that phenyl and benzocyclobutenyl derivatives of 1,4‐benzodioxin interconvert before fragmentation at low internal energy. The mechanisms of the two major fragmentations (HCO and C6H5CO losses) are investigated by means of kinetic energy release determination and appearance energy measurements. From these experiments it is concluded that the fragment ions possess a dibenzopyran structure.
