measurement of the spin lattice relaxation rates of the hydrocarbon protons of the diphytanoyl phosphatidylcholine in a 10 mol % mixture of the branched-chain lipid in a deuterated host lipid , diperdeuteropalmitoyl phosphatidylcholine , showed a discontinuity in the temperature dependence of the proton nmr longitudinal relaxation rates of the branched-chain lipid in the region of the gel to liquid crystalline phase transition temperature of the deuterated dipalmitoyl phosphatidylcholine host lipid .
