The photophysical mechanism by which nucleosides dissipate energy after UV light irradiation is still under debate. Here the authors, using ultrafast time resolved optical spectroscopies and quantum chemical computations, resolve the early steps of such mechanism in uridine and 5-methyluridine in aqueous solution.
