(a) Simulated 2D 15N-1H/15N correlation spectra (open circles) of an ideal β-hairpin as a function of (τ, ρ) angles. Only the frequencies of the seven labeled residues are shown. Gray lines illustrate the orientation-dependent elliptical patterns on which the strand resonances fall. The best-fit spectrum, near (τ = 70°, ρ = 220°), does not fit the experimental spectrum (solid circles) well. (b) The ideal hairpin conformation.
