Nonvalence bound state (NBS) is a unique anionic state where an excess electron is loosely
bound to a neutral molecule in long-range potentials. Since Fermi and Teller first proposed …

Photoactive proteins that efficiently and selectively transfer light energy into a physical
response are ubiquitous in nature. The small molecule chromophores that lie at the heart of …

In an effort to illuminate why nature has chosen a particular set of bio-molecular 'building-
blocks' for life, recent years have seen an up-surge of gas-phase spectroscopy experiments …

The phenol molecule is a prototype for non-adiabatic dynamics and the excited-state
photochemistry of biomolecules. In this article, we report a joint theoretical and experimental …

The Green Fluorescent Protein (GFP), which is widely used in bioimaging, is known to
undergo light-induced redox transformations. Electron transfer is thought to occur resonantly …

The excess electron in the dipole-bound state (DBS) of the anion is found to be recaptured
into the excited valence orbital localized at the positive end of the dipole, leading to the …

Isolated model anion chromophores of the green and cyan fluorescent proteins were
generated in an electrospray ion source, and their photodetachment spectra were recorded …

To understand how photoactive proteins function, it is necessary to understand the
photoresponse of the chromophore. Photoactive yellow protein (PYP) is a prototypical …

Green fluorescent protein (GFP) continues to play an important role in the biological and
biochemical sciences as an efficient fluorescent probe and is also known to undergo light …

Green fluorescent protein (GFP), together with its family of variants, is the most widely used
fluorescent protein for in vivo imaging. Numerous spectroscopic studies of the isolated GFP …
