Abstract: The photoionization and photodissociative ionization processes of p-nitrotoluene(C7H7NO2) have been studied using the photoionization mass spectrometry wlth synchrotronradiation(SR) as the light source- The ionization potential (PIA) of the ionic fragment from the SRphotodissociative ionization of C7H7NO2, have been measured.Based on the mass spectra of C7H7NO2, obtained with SRpho-tolonization and the relationship of energy in the processes, the most possible channels ofphotodissociative ionization of p-nltrotoluene have been analyzed.

Key words: Synchrotron radiation, Photoionization, Mass spectrum, Ionization potential, p-Nitrotoluene
