Coherent Vibrational Wave Packet Motion in Er Cry4a Proteins Monitors the Redox State of the Flavin Chromophore

Abstract Cryptochromes are blue-light-sensitive flavoproteins that play central roles in biological function. In European robin (Erithacus rubecula) ErCry4a proteins, optical excitation of their flavin chromophore forms a long-lived radical pair through a sequence of electron-tra...

A Theoretical Investigation of Nonadiabatic Dynamics and Time-Resolved NEXAFS Spectra of Uracil

Abstract 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...
