Effect of water and pressure on the temperature-dependent relaxation dynamics of prilocaine. (a,c) Comparison of the ambient-pressure dielectric loss spectra of hydrated and pure prilocaine at 243 K (a), and of the dielectric loss spectra at 240.5 K of pure prilocaine at ambient (1 bar) and high (1000 bar) pressure (c). Continuous lines are fits. Insets: same data in ac conductivity representation. (b,d) Arrhenius plot of the primary relaxation times τ of pure and hydrated prilocaine (b) at ambient pressure, and of pure prilocaine at 1000 bar (d). Continuous lines are fits with the Vogel-Fulcher-Tammann Eq. 1.
