Abstract
X-RAY Photoelectron Spectroscopy (XPS) has many advantages for studying, in situ, the photo-induced decomposition of inorganic molecular ions; this is shown by our data on the radiolysis of NaClO3, sodium chlorate, using the standard Mg (Kα) anode [1,254 eV, λ ≃ 10Å] in our AEI ES200B photoelectron spectrometer. We have already examined1 the decomposition kinetics of NaClO4 and NaClO3, when the final products of irradiation were found to be a defect NaCl phase together with molecular oxygen (detected by mass spectrometry). We report here some further low temperature XPS studies on the NaClO3 system, where strong evidence for the presence of trapped oxygen species in the initial stages of irradiation has emerged.
