Abstract

The stepwise ionization processes of 1,2-dihydroxybenzene vapor at 315–275 and 266 nm were studied by the techniques of mass spectrometry, total ionization current spectroscopy, and zero electron kinetic energy spectroscopy. A two-step ionization process yielding the molecular ion prevails at a laser intensity up to ∼107W/cm2. As the radiation intensity increases, fragmentation takes place via the dissociation of molecular and fragment ions due to absorption of one additional photon. The formation pathways of principal fragment ions are discussed.
