Normalized diffusive intensity decays from STE PFG 1H NMR spectra (35°C) of various molecular-weight PEG (as indicated) confined within positively magnetically aligned q = 4.5 bicelles. Results for PEG 4600 are not shown, to avoid cluttering the figure. Symbols represent different diffusion times: 210 ms (solid triangles), 410 ms (open circles), 610 ms (solid squares), 810 ms (open diamonds), and 1010 ms (solid inverted triangles). The solid lines are fits using Eq. 2.
