"BIOLOGICAL PHOTORECEPTORS contain chromophores that absorb photons and then undergo rapid chemical transformation on their excited states, eventually leading to light-induced signal transduction. Owing to the quantum nature of electronically excited states and nuclear quantum coherences that often accompany excited-state molecular dynamics, quantum mechanics is required to describe these photoactivated dynamics in biological photoreceptors." https://lnkd.in/eRUdQZj View in LinkedIn
