Structural dynamics of green fluorescent protein was studied by femtosecond time-resolved impulsive Raman spectroscopy. The excited-state vibrational spectra of the protein with three different chromophore forms were obtained and they revealed the...

The substituent effect on the excited-state dynamics of bis-diimine Cu(I) complexes was investigated by femtosecond time-resolved absorption spectroscopy with the S-1 <-- S-0 metal-to-ligand charge transfer (MLCT) photoexcitation. The time-reso...

We studied the signaling-state formation of a BLUF (blue light using FAD) protein, PapB, from the purple bacterium Rhodopseudomonas palustris, using femtosecond time-resolved absorption spectroscopy. Upon photoexcitation of the dark state, FADH(ce...

Light absorption by the photoreceptor microbial rhodopsin triggers trans cis isomerization of the retinal chromophore surrounded by seven transmembrane alpha-helices. Sensory rhodopsin I (SRI) is a dual functional photosensory rhodopsin both for p...

The Cu(I) complexes having phenanthroline derivatives as ligands are known to exhibit photo-induced 'flattening' structural change in the metal-to-ligand charge transfer (MLCT) excited state. Our recent ultrafast spectroscopic studies of [Cu(dmphe...
