ResumoRecent experiments in low-intensity fluorescence spectrometry, flash photolysis and continuous photolysis at 300°K in an aqueous medium have provided data for uracil and thymine from which all the pertinent phenomenological characteristics (Φfl0′, Φisc0′, Φ′chem) of the 0′ level can be evaluated. It is necessary to postulate considerable internal conversion 1S → 0S with τic ≈ 1–2 × 10−12 sec, this process correlating with the dielectric relaxation time of water.
