We report on gas-phase experimental and theoretical studies on the neutral form of the green-fluorescent protein (GFP) chromophore using six different models, each carrying a spectator positive charge. Theoretical studies were carried out to quantify the effect of the spectator charge on the absorption maximum of the true neutral. The study also includes models having the possibility of forming intra-molecular hydrogen bonds, and their effect on the absorption profile is analyzed. The charge redistribution caused by a strong intra-molecular hydrogen bond was found to give rise to a red shift in going from non-hydrogen bonded to hydrogen bonded models. For the non-hydrogen bonded models, the length of the side chain as well as the group carrying the spectator charge, was varied to explore the possibility of shifts in absorption maximum due to these variations. No shifts were observed. The implications of these results in tuning the absorption maximum of the neutral form of the GFP chromophores are discussed.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
