WebAbstract— We examined the emission spectra of tyrosine- and tryptophan-containing proteins using one-photon (270–310 nm) and two-photon (565–610 nm) excitation. Emission spectra for two-photon excitation of native and denatured human serum albumin and of three purine nucleoside phosphorylases indicated an absence of the tyrosine … WebAug 4, 2013 · Fluorescence emission spectrum of tryptophan in water is proportional to the intensity at the excitation wavelength (here 295 nm) and not to the intensity of the excitation maximum (280 nm). Therefore, fluorescence emission cannot be regarded as the result of electronic distribution within the ground state but to the new electronic distribution …
