| Abstract: | Photoionization and photodissociation of ethylene oxide are performed by using a time-of-flight mass spectrometer(TOF-MS) with vacuum ultraviolet(VUV) photons from Hefei synchrotron radiation source. The photoionization mass spectrum and the photoionization ef ficiency(PIE) curves of the fragment ions are measured.The appearance potentials of all the observed ions are obtamed from then PIE curves.From these data, the formation enthalples of some chlef ions have been evaluated Possible channels and their comptition of chssociative photoionization of cthylene oxide have been discussed. |
