Pressure effects on the dynamics of ions and solvent molecules in liquid methanol under ambient and cold conditions: Importance of solvent's H-bonding network

► Pressure dependence of self-diffusion coefficients of ions in CH3OH at 258 and 298 K ► No pressure dependence anomalous property of the diffusion coefficients is observed. ► H-bond lifetime and structural-relaxation time of methanol increase with pressure. ► Whereas for water these values decrease with pressure at a given temperature.
