Abstract
Time of flight (TOF) mass spectrometry is used in conjunction with a variable repelling
voltage technique to elucidate the mechanism by which phenol ionizes and dissociates
under 266 nm pulsed laser irradiation in combination with a 532 nm or 355 nm pulsed
laser. The results suggest that, like benzene, the molecular ion is the predominant
precursor of all ionic species generated in the process. Predominance of
