Tryptophan emission
WebJun 1, 2008 · The effect can be observed in fluorescence emission spectra as a shift of fluorescence maximum resulting from relaxation and reorientation of the local field . In apolar solvents such as 2-propanol the emission maximum of tryptophan can thus be found at 340 nm, whereas in polar solvents such as water that maximum lies at 355 nm (Figure 3). WebAssociations between EOCs and other hydrochemical parameters including excitation emission matrix (EEM) fluorescence indicated positive, significant, and compound-specific correlations between EOCs and tryptophan-, fulvic- and humic-like fluorescence.
