英文摘要	the first excited state of the model green fluorescence protein (gfp) chromophore anion (s-1) and its energy level against the electron-detached neutral radical d-0 state are crucial in determining the photophysics and the photoinduced dynamics of gfp. extensive experimental and theoretical studies, particularly several very recent gas-phase investigations, concluded that s-1 is a bound state in the franck-condon vertical region with respect to d-0. however, what remains unknown and challenging is if s-1 is bound adiabatically, primarily due to lack of accurate experimental measurements as well as due to the close proximity in energy for these two states that even sophisticated high-level ab initio calculations cannot reliably predict. here, we report a negative ion photoelectron spectroscopy study on the model gfp chromophore anion, the deprotonated p-hydroxybenzylidene-2,3-dimethylimidazolinone anion (hbdi-) taken under low-temperature conditions with improved energy resolution. despite the considerable size and low symmetry of the molecule, resolved vibrational structures were obtained with the 0-0 transition being the most intense peak, the adiabatic (ade) and vertical detachment (vde) energies therefore are determined both to be 2.73 +/- 0.01 ev, indicating that the detached d-0 state is 0.16 ev higher in energy than the photon excited s-1 state. the accurate ade and vde values and the well-resolved photoelectron spectra reported here provide much needed robust benchmarks for future theoretical investigations.
