Probing and Modeling the Absorption of Retinal Protein Chromophores in Vacuo

Abstract

Seeing the light: A joint experimental and theoretical approach delivers the free gas-phase high-resolution absorption spectrum of the chromophore conformations implicated in the spectroscopy of retinal proteins (see scheme). Notably, many retinal pigments absorb close to the gas-phase value. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
