a

Data taken from [18, 96].

b

PM was determined as the mean of the maximal and the minimal evaluation, which takes the uncertainty of the location of the spin label nitroxide group into account [94, 95]. Mean values ± differences between mean values and maximal (minimal) evaluations are indicated.

c

The thickness of the water layer is the same as the hydrocarbon region.
