(a) Incoherent intermediate structure factor for dh-DPPC as measured by QENS with two instruments (open symbols) and predicted by the simulations (continuous lines). Data are shown for two different momentum transfers Q at 370 K. (b) Incoherent intermediate structure factor at three different Q-values at 370 K (open symbols) as extracted from molecular dynamics. The continuous solid line is a best fit using Eq. 6 while the dashed lines are partial representations of the processes involved in the full scattering function.
