text: In addition to different orientation at different pH, the pH dependent differences in the spectra of uracil and thymine can also be caused by the presence of different tautomeric forms of the molecules: Thymine and uracil can be deprotonated at the N1 or N3 position, which leads to a tautomeric equilibrium between both deprotonated forms.
