The theta-pinch flash lamp has been investigated for applications to photochemical studies. Attempts to find evidence for two photon absorption processes in several systems, including solutions of perylene in ethanol, subjected to the intense light flux from the theta-pinch lamp were not successful. Similarly, a search for the absorption spectrum of the phenyl radical in the liquid phase transient photolysis products from the theta-pinch flash photolysis of mercury diphenyl failed. A study of the theta-pinch and conventional flash photolysis of biacetyl pointed up the need for control of the cooling of the theta-pinch lamp in photochemical investigations. The low intensity 2537A, flash intensity and theta-pinch intensity photolysis of silyl iodide has been carried out at room temperature in the presence of scavenger andor moderating gases. Some evidence is available for the formation of hot silyl radicals. This research represents the first comprehensive study of the photolysis of silyl iodide. Author
