Simulations for energy transfer efficiencies between donors and acceptors in lipid bilayers (Eqn. 6). Donors and acceptors are assumed to be located at similar depths in the bilayers (l = 6 Å), and energy transfer is calculated for a single plane of acceptors (energy transfer to the second leaflet is not accounted for); 72 Å² was taken as the area occupied by each lipid. a Dependence of energy transfer efficiencies on R ₀ and acceptor concentration (no acceptor exclusion area is accounted for). b Dependence of energy transfer efficiencies on the radius of the circular area around the donor from which acceptors are excluded (a value of 40 Å was used for R ₀)
