Abstract: | Time-resolved fluorescence spectrum of Quinacrine Mustard in acetate buffer solution (pH 4.6) under excitation of subnanosecond laser pulses is reported. The decay curve has been found to consist of three exponential components, whose amplitudes depend on both excitation and observation wavelengths. This behaviour has been attributed to the formation of three protonated species of the molecule in the excited state. |
