Analysis (A) Inversion recovery experiments where 20 of 10,000 simulations are shown (B) CPMG experiments, where 20 of 10,000 simulations are shown (C) PFGSTE NMR experiments, where 20 of 14,000 simulations are shown. Resulting distributions of (D) \({T}_{1}\), (E) \({T}_{2}\), (F) \({\tau }_{c}\), (G) \({D}_{T}\) estimated from relaxometry (H) \({D}_{t}\) measured from 53Cr PFGSTE NMR, where P is probability. Skewed Gaussian fits are in orange and symmetric gaussian fits are marked with a black dashed line. Uncertainties (+/− σ) are likewise annotated.
