โฆ Synopsis
The process of singlet-singlet resonance energy transfh between rhodamiue 6G (donor) and malachite green (acceptor) has been studied with a picosecond laser z streak camera system. Unlike previous investigations, the measurements were conducted in a low viscosity solvent (ethanol) at room temperature. The donor fiuorescenee decay function was found to be in agreement with that predicted by the Fijrs$er theory over a tenfold r-e of acceptor concentrations (10" M to lo-' M) and up to a limiting time resolution of 10 ps. An average Ro value of 52.5 A was obtained from the fluorescence decay curves, in reasonable agreement with the value of 48 A calculated from spectroscopic data.
