Dilute aqueous solutions were irradiated between room temperature and -8° in the liquid phase to determine the primary radiation chemical yields of the decomposition products of water. The application of normal scavenger methods showed a linear decrease in GH and GOH and an increase in Geaq- with decreasing temperature below 0°, although these yields were temperature independent above the equilibrium melting point. This seems to be the first observation of an abrupt discontinuity due to supercooling in any property of water. GH2O2 was not affected by supercooling, which suggests that the mechanism of H2O2 formation is probably not the combination of two OH radicals.
