From: Role of Hydrogen Bonding in Green Fluorescent Protein-like Chromophore Emission
Fluorescent redshift of the modified chromophore with hydrogen bonding network consisting of hydrogen and water. Molecular configurations of the modified chromophore with hydrogen in the (a) absence and (b) presence of water molecules, added hydrogen atom are highlighted in blue. (c) The computed electronic energy levels and photo-emission transitions of the two excited-state structures and the original modified chromophore. The orbital transitions for the calculated photo-emission peak of the chromophore with hydrogen in the (d) absence and (e) presence of water molecules in aqueous solution. The green dotted bonds denote hydrogen bonding.
