Abstract

A study was conducted, using wavelength and time-resolved pump-probe and pump-dump-probe spectroscopy, to investigate the excited and ground-state photoinduced dynamics of the green fluorescent protein (GFP) chromophore and 4'-hydroxybenzylidene-2,3-dimethylimidazolinone (HBDI). The result identifies two pathways such as a 1-photon excited-state twisting, and a 2-photon ionized process.

Abstract

The first definitive assignments of the vibrational spectra of a model green fluorescent protein (GFP) chromophore is presented by using isotope labeling, which is useful for establishing the nature of the changes in the vibrational spectrum because of the protein environment. The observation reveals that these changes can be related to the structure of the chromophore within the protein and linked to the absorption and emission spectra observed for GFPs.
