## Abstract Apparatus is described for experimentally determining diffusion coefficients in dense‐gas systems to pressures of 15,000 lb./sq. in. abs. Tests were made with the hydrogen‐nitrogen and methane‐ethane systems at 104°, 139°, and 171°F. to 10,000 lb./sq. in. abs. and with the nitrogen‐meth

✦ Synopsis
The rotational correlation functions, calculated from the ~5 (Al) infrared absorption band ofCHaD compressed with various gases, has been compared with those computed by the Gordon M or J models. The J model gives the most accurate fit to the experimental results.

A simple uniform-pressure diffusion apparatus has been used to measure the diffusivities of the gaseous fluorocarbons CF4 and CF2C12 in air at atmospheric pressure and room temperature (293 K). The diffusion coefficients arc found to be D(CF4-air) = 0.121 cm2s-r and D(CFaCla-air) = 0.098 cm2s-\*. Th
