A study reported in The Journal of Physical Chemistry Letters (Wang et al., 2021, 12, 2370) of "boosted mobility" measured by diffusion NMR experiments contains significant errors in data analysis and interpretation. We carefully reanalyzed the same data and find no evidence of boosted mobility, and we identify several sources of error.
