    Abstract

    Far-infrared RAIRS spectroscopy employing synchrotron radiation as a source, has been used to study the interaction of SnCl4 and water on thin-film silica and carbon surfaces. This has been made possible by growing the thin films on a highly reflecting tungsten substrate, enabling the conventional RAIRS geometry to be used. In addition to the observation of a strongly chemisorbed species on the silica surface the spectra from both surfaces indicate the presence of a more weakly bound complex containing both water and SnCl4.
