Abstract
The diffusion coefficients of atomic oxygen in O2, N2, Ar, and He, and of atomic nitrogen in N2, have been measured as a function of pressure and temperature, using a previously described method.The rigid sphere collision diameters of atomic oxygen and atomic nitrogen at 280 °K were calculated as 2.65 Å and 2.75 Å respectively. The temperature dependence of the diffusion coefficients of O in O2 and N in N2 yielded the following Lennard-Jones parameters:[ ]
