Diffusion coefficients at infinite dilution of carbon dioxide and methane in water, ethanol, cyclohexane, toluene, methanol, and acetone: A PFG-NMR and MD simulation study

•Diffusion coefficients at infinite dilution were determined by NMR and molecular simulations.•NMR yields precise results for the diffusion coefficient from simple equilibrium measurements.•Data for CO2 and CH4 in six solvents are provided and evaluated.•Results are compared to prediction methods from the literature.
