The photoionization-dissociation pattern of 1,4-dioxane has been studied by molecular beam. VUV from Synchrotron Radiation and TOF mass spectrometry. The possible fragmentation channel and structures of ion fragments(m/e 41 28 29 58 57)have been discussed on the basis of PIE curves, and a rearrangement reaction mechanism for the photoionization-dissociation of 1,4-dioxane has been proposed.

Key words: 1,4-dioxne, Synchrotron radiation, Photoionization and dissociation, Rearrangement reaction
