Calculated heat capacity of the ternary mixture at the critical composition. The heat capacity of the ternary C–DPPC–DOPC mixture was obtained by using Eq. 9 together with ΔH =–19.2 kcal/mol (–32.4 kBTr), the heat of reaction used in calculating the phase diagram in Fig. 1. At the critical temperature, there is a jump in the temperature derivative of the concentration of complexes and a corresponding jump in the heat capacity. A jump in the temperature derivative of the first moment of the deuterium NMR is also calculated at the ternary critical point.
