Hydration states of K8(Si4L6) and K12(Ga4L6) cages. Hydration number \(Z_{{\mathrm{IB}}}^{{\mathrm{ap}}}\) plotted as a function of stoichiometric ionic strength I for K12(Ga4L6) (red and orange points, R2 = 0.82) and K8(Si4L6) cages (blue points, R2 = 0.81). Error bars represent 95% confidence intervals propagated from fit parameters of Ctot and Gtot. Each point was calculated from a set of broadband distributed circuit parameters shown in Fig. 2
