Comment on “Self-diffusion near the liquid–vapor critical point” [J. Chem. Phys. 114, 4912 (2001)

Abstract

Drozdov and Tucker [J. Chem. Phys. 114, 4912 (2001)] have computed the self-diffusion coefficient along a near-critical isotherm showing anomalous slowing of molecular motion near the critical density and cite some experiments in support. A considered examination of the best literature data shows no such anomaly near neat liquid critical or mixture consolute points.
