EPR spectra calculated for the tether-in-a-cone model as a function of various angles. For all calculations, p = 8 Å, q = 6 Å, and μmax = 30°. (A) α = β = γ = 0° and ψ1 = ζ2 = ψ2 = 0°. (B) α = 0°, β = 90°, γ = 0°, and ψ1 = ζ2 = ψ2 = 0°. (C) α = β = γ = 0°, ψ1 = 0°, ζ2 = 0°, and ψ2 = 90°. (D) α = β = γ = 0°, ψ1 = 90°, ζ2 = 0°, and ψ2 = 90°. (E) α = β = γ = 0°, ψ1 = 90°, ζ2 = 90°, and ψ2 = 90°. (F) α = β = γ = 0°, ψ1 = 90°, ζ2 = 180°, and ψ2 = 90°. The insets (top right) show a histogram representing P(R). The diagrams to the left of each panel represent the relative orientation of the cones as determined by ψ1, ζ2, and ψ2.
