Given that the prebiotic inventory necessary for life was likely produced photochemically, I talk about how we can experimentally determine how effective the ultraviolet (UV) photochemistry is versus bimolecular reactions that happen in the absence of the UV light (‘dark chemistry’). I discuss what stellar UV fields are necessary for building up this prebiotic inventory on exoplanets, considering both the quiescent stellar emission and the effect of flares and coronal mass ejections.
