This paper summarizes some of the data in the literature on the effects of phase on chemical reactions induced in organic systems by light, ionizing radiation and nuclear transformations. It also presents new data which show that: (1) the ratio of HI to I/sub 2/ produced in the radiolysis of pure isopropyl iodide with Co/sup 60/ gamma -rays is about tenfold higher in the solid phase at --190 deg than in the liquid at room temperature; (2) the yield of iodine from the radiolysis of isopropyl iodide in either the liquid or solid is dependent on the past history of irradiation of the sample in the other phase; (3) when the spectrum of ethyl iodide glass at --190 deg is examined after exposure of the solid to 2537 A. light, little or no change is observed as a result of the irradiation, but when the glass is then melted amd immediately refrozen, an absorption peak appears at 3700 A.; a similar effect is caused by the self-irradiation of tritiated ethyl iodide glass; (4) the ratio of HI to I/ sub 2/ produced by the photolysis of ethyl iodide is approximately ten-fold higher in the glass at --190 deg than in the liquid at room temperature.
