Table 1

Effective TOT layer thicknesses (in Å) as a function of the basal spacing for the 2WL, 3WL, and 5WL systems. The layer thickness that yields an interlayer water density of 1 kg dm−3 is denoted ‘Water density.’ The value calculated from the Cl distance of closest approach to the surface is denoted ‘Closest approach.’ The value calculated from the location of the Na+ density peaks is denoted ‘Na peaks.’
