The unimolecular fragmentation reactions of 28 protonated nitroarenes, occurring on the metastable ion time-scale, are reported. In addition, the collision-induced fragmentation of the same species have been studied at 10 eV and at 50 eV collision energy. When an OH, COOH or NH, substituent is ortho

OH+ or OD+ ions were generated by collisionally induced charge reversal of the corresponding anions and then submitted to collisionally induced dissociation to H+ and D+. The resulting ion kinetic energy spectra showed multiple vibrational time structure which were assigned to pred~sociations from t
