摘要：

Ionic photofragmentation of SO2 in the sulfur 2p and 2s regions has been investigated using monochromatic synchrotron radiation. Multistop time-of-flight mass spectrometry was used to collect photoelectron-photoion coincidence (PEPICO), photoion-photoion coincidence (PIPICO) and photoelectron-photoion-photoion coincidence (PEPIPICO) spectra simultaneously. Partial ion yields and partial ion-pair yields have been determined. Dissociation mechanisms of the productions of ion-pairs O+-S+ and O+-SO+ have been discussed briefly. (c) 2005 Elsevier B.V.
