Table 1. Splittings, Δ ν, and corresponding order parameters, SCD, for the resolved peaks of the 2H NMR spectra of POPC-d 31/POPG (7∶3) (Figure 1) in the absence and presence of SP-B (1–25,63–78) (Super Mini-B).

The splittings quoted derive from a single experiment; however the uncertainty has been estimated based on the standard deviation in splittings derived from 5 separate control experiments with the same lipid composition.
