Abstract Electron ionization (EI) and liquid secondary ionization mass spectra (LSIMS) of 30 coelenterazine analogues were examined by use of linked scanning at constant B/E and the fragmentation rules upon EI and LSIMS have been established. On the basis of these results the structures of intermediates in the chemiluminescence of these compounds have been deduced as monooxygenated compounds and the possible mechanisms of chemiluinescence of these compounds are discussed.
