Sulfur K-edge photofragmentation of ethylene sulfide

Research output: Contribution to journalArticle

Abstract

We have investigated the photofragmentation properties of the three-membered ring heterocyclic molecule ethylene sulfide or thiirane, C2H4S, by time-of-flight mass spectroscopy. Positive ions have been collected as a function of photon energy around the S K ionization threshold. Branching ratios were derived for all detected ions, which are informative of the decay dynamics and photofragmentation patterns of the core-excited species. We present a new assignment of the spectral features around the S K-edge. (C) 2010 American Institute of Physics. [doi:10.1063/1.3457946]
