... in 50% of the maximal efficacy (R 0 ). As indicated by the Fo ¨ rster equation, the efficiency of transfer varies inversely with the 6th-power of the distance. The extreme steepness of the relationship ... transfer, the efficiency of transfer is deter- mined both by the orientation of the energy transfer partners and by the distance between them [28]. The fa...
