Table 2. Two Sets of Ion Radiia.
VDW radius | RDF radius | |
---|---|---|
Na+ | 1.4 Å | 2.3 Å |
K+ | 1.8 Å | 2.6 Å |
Cl– | 2.3 Å | 4.0 Å |
The van der Waals (VDW) radii are taken from the CHARMM36 ion VDW radii. The radial distribution function (RDF) radii are the first-peak positions of the ion–lipid carbonyl oxygen RDFs from the MD simulations.
