The road not taken: Many paths diverge on the road to photodamage prevention in cytosine. Previous work has focused on determining a dominant relaxation mechanism. Ab initio excited‐state molecular dynamics studies show that there is not a single dominant path, but rather many distinct paths involving different quenching mechanisms (see figure).
