QUANTUM YIELD OF PHOTOHYDRATION FOR DIMETHYLURACIL. CONCENTRATION AND WAVELENGTH DEPENDENCE*

Abstract

Abstract— The quantum yields for the photohydration of dimethyluracil were determined for concentrations in the range 5 × 10 ‐ ‐ 1 ‐ ‐ 1 × 10 ‐ ‐ 3 M by use of 240–280 nm irradiation. The average quantum yield (0.0139 f 0.0005) was independent of both concentration and irradiation wavelength.
