Table 10. Self Diffusion Coefficient D (m²·s^–1) of Liquid Sulfolane Estimated From Simulations Using the Three Force Fields, at Temperature T = 303 K and Pressure p = 1 bar^a.

force field	D/10–11·m2·s–1b	ΔD (%)
force field of ref (2)	0.06 ± 0.001	–99.59
OPLS	7.12 ± 0.08	–51.63
this work	11.89 ± 0.4	–19.16

^aExperimentally determined value of diffusion constant obtained through extrapolation from data in ref (2) is 14.72 × 10^–11 m²·s^–1.

^bThe expanded uncertainty (U) is reported at 95% level of confidence.
