Ultrafast Electron Diffraction Reveals Dark Structures of the Biological Chromophore Indole

Abstract

Shedding a light on the dark: Ultrafast electron diffraction of the tryptophan chromophore, indole (see determined structure; C orange, N blue, H white), reveals the involvement of dark structures in the nonradiative pathways of the isolated molecule. Such dark structures have to be part of the understanding of biological chromophore stability. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
