Fig. 2

A 53Cr saturation recovery spectra at 20 °C. B 53Cr CPMG spectra at 20 °C. C Data fit to determine \({T}_{1}\) and (D) \({T}_{2}\) as a function of temperature. E Diagram to show Arrhenius relationship to determine the temperature dependence of the \({T}_{1}\), \({T}_{2}\) and (F) \({\tau }_{c}\). The error bars (+/- σ) in this figure were determined via analysis of Monte Carlo simulations as later described. Tables of \({T}_{1}\), \({T}_{2}\) and \({\tau }_{c}\) are provided in Tables S4–S6 of the Supplementary Information. Note, the units of concentration are in molality.
