Two-photon excited fluorescence excitation spectra using circularly and linearly polarized light are presented for the aromatic amino acids tryptophan, tyrosine (amide form) and phenylalanine in neutral aqueous solution at room temperature. The wavelength range was 440-620 nm, corresponding to 220-3
Fluorescence quenching of nine aromtic hydrocarbons by cesium chloride in methmolic solution has been meassured t~Sing'pulse fluo&netrY. A log-log relationship between kq, the rate corstant for quenching by CsCI, and kS+T, the inter- system crossing rate of the fluor, appears to,be applicable to the
Ruorescence quenching of aromatic molecules by inorganic anions in H20-EtOH mixtures at 300 K has been studied quantitatively. A linear relationship between log k. (kq is the quenching rate constant) and AC (the free energy change in electron transfer) is obtained indicating that the &on-mduced quen
