Abstract: Time-of-flight mass spectrometry of several aromatic molecules were investigated in onestep UV laser desorption/ionization. Results show that benzo[e]pyrene is softly-ionized byresonant two-photo ionization, and that fluoranthene is ionized via three-photo ionization.2,5-dihydrobenzic acid and cinnamic acid can also be ionized by pulsed UV laser and molecule-ion reactions occured during desorption and ionization processes.
Key words: aromatic hydrocarbons, UV laser ionization, time-of-flight mass spectrometry
