Figure 3.

Upper panel: cartoon representation of the labelled amides (colored segments) and their positions relative to the membrane center. Lower panel: Dependence of Δω_n/cos(α) on r_n obtained for LAP-An peptides in DLPC and POPC membranes, as indicated. The lines are global fits of these data to Eq. (3), which yielded A = 24.16 cm⁻¹, β = 0.43 Å⁻¹ for DLPC and β = 0.38 Å⁻¹ for POPC.
