A Theoretical Investigation of Nonadiabatic Dynamics and Time-Resolved NEXAFS Spectra of Uracil
Uracil, a fundamental RNA nucleobase, exhibits complex excited-state dynamics governed by nonadiabatic processes that prevent photodamage. Upon photoexcitation, population initially reaches the bright ππ* (S2) state and subsequently relaxes to the dark nπ* (S1) state via conical intersections, before returning to the g...
