Experimental self-diffusivities of
gases, vapors, and liquids obtained
by means of tracer techniques and nuclear magnetic resonance are reviewed.
The considered substances range from noble gases and simple diatomics
(nitrogen, oxygen, carbon monoxide, etc.) to complex organic molecules,
such as phenolphthalein dimethyl ether and 2-(α-methylbenzylamino)-5-nitropyridine,
although polymers have not been included. Some comments on the applicability
of neutron scattering to the determination of self-diffusion coefficients
are also made. All the experimental results of the investigated systems
are given as Supporting Information, whereas
the references, temperatures, and pressures of these data and the
main features of the measurement methods are compiled and classified.
