|---|---|---|---|---|
| lipid | temp. (K) | old FF | new FF | exp. |
| DMPC | 303 | 4.1 | 2.7 | 9.0; 1.6b |
| POPC | 303 | 3.9 | 2.5 | 10.7 |
| DPPC | 323 | 7.3 | 5.4 | 7; 1.0b |
The uncertainties in the calculated diffusion coefficients are all within ±1.1 cm2/s.
Measurement was conducted above the phase transition temperature (296 K for DMPC and 315 K for DPPC).
