摘　　要：The photoionization and photodissociative ionization processes of azoxybenzene (C12H10N2O,AOB) have been studied using the photoionization mass spectrometry with vacuum ultraviolet synchrotron radiation (SR) as the light source. The ionization potential (IP) of this molecule and four appearance potentials (AP) of the important ionic fragments from the SR photodissociative ionization of AOB have been measured. On the basis of the IP(C12H10N2O) and AP() measured in this experiment,the dissociative energy D0(-N2OC6H5) has been evaluated. Based on the results of the mass spectroscopy of AOB,the possible channels of photodissociative ionization of AOB have been analyzed.The photoionization and photodissociative ionization processes of azoxybenzene (C12H10N2O,AOB) have been studied using the photoionization mass spectrometry with vacuum ultraviolet synchrotron radiation (SR) as the light source.
