title: Analysis of the composition of mixed lipid phases by the moments of 2H NMR spectra.
abstract: The use of (2)H NMR spectral moments to determine the composition of biphasic lipid mixtures is outlined. The analysis has been applied to phosphatidylethanolamine-cholesterol (1:1), potassium palmitate, 30% (wt/wt) water and phosphatidylcholine-cholesterol (4:1) systems, as well as to membrances of Escherichia coli during phase transitions. The advantages and disadvantages of the use of spectral moments to determine fractions of coexistent phases are discussed.
