Abstract The large change in the electronic absorption spectrum of cytidine on going from an aqueous to an aprotic medium is attributed to the existence of a hydrogen bonded solvent‐solute complex in solvents capable of donating a proton. The spectrum of cytidine in a variety of solvents and the spectra of a number of nontautomerising model compounds are presented. The tautomerisin of cytidine and its biological implications are discussed.
