Figure 8.8.
Fluorescence decays of five uracils in room-temperature aqueous solutions (~2.5 × 10−3 mol/dm3) at 330 nm: (in increasing order) uracil, 6-methyluracil, 1,3-dimethyluracil, 5-methyluracil (thymine), and 5-fluorouracil. Also shown is the 330 fs (FWHM) Gaussian apparatus function. The inset shows the same curves on a semilog scale. Reproduced with permission of J. Am. Chem. Soc. (2006) 607.
