The photoionization and photodissociative ionization processes of m-nitroaniline (CeH6N2O2) have been investigated with synchrotron radiation (SR). The ionization potential (IP) of m-nitroaniline and the appearance potentials (AP) of the ionic fragments from the SR dissociative photoionization of C6H6N2O2 have been measured. Based on the IP(C6H6N2O2), AP(C6H6N+) and the related molecular formation enthalpies, D0(O2N-C6H6N+ )and △Hf(C6H6N+) have been evaluated. The mass spectrum of C6H6N2O2 obtained with SR photoionization has been presented. The most possible channels of dissociative photoionization have been discussed.
