Excitation spectra for triplet state formation and fluorescence emission from uracil and thymine in neutral aqueous solution at room temperature are anomalous when compared to the absorption spectra of uracil and thymine. The experimental data are critically examined with respect to three molecular models; Model 1, which is characterized by increased intersystem crossing from higher vibrational levels of S(1); Model 2, in which fluorescence is attributed to a (pi,pi(*)) state, whereas… CONTINUE READING
