Abstract:

HeⅠ photoelectron spectrum of isotopic 18O2 molecules has been firstly recorded on a double-chambers UPS machine Ⅱ which was built specifically to detect transient species. In comparison with UPS results of oxygen molecles 16O2 it is found that the reduction of adiabatic ionization potentials IPs, the decresae of vibrational intervals and the change of intensity of vibrational components on each ionic state of isotopic 18O2 molecules obviously appear on the UPS spectrum.

Key words: Isotopic 18O2 Molecules, He I Photoelectron Spectroscopy(UPS)
