Correlation of TrpGly and GlyTrp Rotamer Structure with W7 and W10 UV Resonance Raman Modes and Fluorescence Emission Shifts
Spectra for TrpGly at pH 5.5 (dotted line) and pH 9.3 (dot-dash line), and GlyTrp at pH 5.5 (solid line) and pH 9.3 (bold line). (a) Fluorescence emission spectra, 279 nm excitation, 2 nm slits, 1 sec acquisition time, and 1 nm step size. The GlyTrp emission spectra are normalized to those for TrpGly. (b) UVRR W10 band.
