Proton Dynamics and Transport in a Protic Ionic Liquid Revealed by Multinuclear Solid-State NMR.
Variable-temperature solid-state NMR (1H, 13C, 19F, and 15N), thermogravimetric, and electrical conductivity studies were employed to investigate molecular dynamics and proton transport in protonated 1-methylimidazolium triflate ([HMIM][Tf]). Two distinct dynamic processes were identified: the reorientation of the imid...
