Assume That Excitation E Fluorescence F And Phosphorescence P Spectra For Tryptophan Molecule In An Aqueous Solutio 1 (154.44 KiB) Viewed 36 times

Assume that excitation (E), fluorescence(F) and phosphorescence(P) spectra for tryptophan molecule in an aqueous solution were obtained at 77K and are displayed in the following Figure. (a) Calculate roughly the Stokes shift in eV. Neglect phosphorescence in this case. (b) Describe any change(s) expected for the phosphorescence spectrum of the same molecule obtained at 300K. Explain the reason(s) for your answer. Relative intensity 200 300 400 Wavelength, nm 500 600
