| The first application of infrared spectroscopy to surface chemistry was more than 50 years ago but it is only recently that wet solid surfaces, which are ubiquitous in nature and in technology, have begun to be explored with this technique. The most popular approach has been via attenuated total reflection (ATR) crystals coated with thin solid particle films. Such methods readily provide new details of the molecular nature of adsorption, adhesion, and photoinduced processes which can occur at the surfaces of wet solids in natural environments. In this talk the principles, achievements and limitations of the ATR-IR method applied to wet particle films will be discussed using examples from recent research and from recent geochemical publications. |
