Abstract:We report on the fragmentation of ionized pyridine (C 5 H 5 N) molecules by focused 50 fs, 800 nm laser pulses. Such ionization produces several metastable ionic states that fragment within the field-free drift region of a reflectron-type time of flight mass spectrometer, with one particular metastable dissociation being the leading fragmentation process. Because the time of flight is no longer dependent in a simple way on the mass of the ion, the metastable decay is manifested as an unfocused peak on the mass… Show more
Intense-field stability of photoionization and fragmentation are compared for aniline (C6H5–NH2) and nitrobenzene (C6H5–NO2), with amine vs. nitro substitutions explored.
