The Application of Concentration-Distance Profiling Raman Microspectroscopy to the Study of the Photoinduced Crystallization of Triethylenediamine Triiodide Upon a Silver Electrode
Abstract
The technique of concentration-distance profiling Raman microspectroscopy has been applied to the system silver/triethylenediamine, HClO4, Nal, H2O) to map out the variations in the concentrations of species with distance from the electrode surface. Under anodic conditions crystals of triethylenediamine triiodide grow from the site of laser illumination. These have also been studied; they extend some 200 um from the silver electrode surface with maximum population at about 40 microns. Under cathodic conditions the crystals are destroyed and the surface is covered with iodide interacting in an ion-parting fashion with diprotonated triethylenediamine, abbreviated DABCO- H22+.
