| Abstract: | The energy transfer mechanism in C 540–rhodamine 6G and C 540–rhodamine B donor–acceptor (D–A) pairs is investigated. The good spectral overlap and the proximity of D–A pair molecules, which is around 60 Å, denote the possibility of resonance energy transfer between the D–A pairs. Energy transfer is studied in two solvent environments. C 540–Rh 6G and C 540–RhB D–A pairs behave in quite different manner in different solvent environments. |
