Pressed alkali halide disks, which are used commonly to obtain the infrared spectra of solid compounds, are found to be convenient matrices in which solid state chemical reactions of organic ions can be examined. These reactions can be induced thermally or by irradiation, and their kinetics can be followed spectroscopically. In thermal decomposition reactions involving weight changes, the kinetic results obtained with these disks be infrared spectroscopy agree with those from the thermogravimetric analysis. In gamma irradiation studies, ion free radicals are trapped readily in these disks even at room temperature, and the decay of these radicals can be followed by electron spin resonance spectroscopy. When the concentrations of these radicals are sufficiently great, their chemistry as well as their absorption spectra can be investigated. Experiments carried out to date indicate that the use of pressed disks can extend the field of solid state chemical kinetics and matrix isolation studies.
