| Abstract: | Abstract— The absorption spectra, lifetimes, extinction coefficients and intersystem crossing quantum yields of the lowest triplet T 1 of 4-thiouridine have been determined both in acetonitrile and in water. An ordering of 1,3(n,π)* and 1,3(π,π)* states is suggested. Triplet quenching rate constants with various pyrimidine bases or amino acids are reported. |
