Molecular‐beam scattering results are analyzed to obtain a consistent and reliable set of potentials for the atom‐molecule interactions N‐N2, N‐O2, O‐N2, O‐O2, N‐NO, and O‐NO, and the molecule‐molecule interactions N2‐N2, N2‐O2, O2‐O2, N2‐NO, O2‐NO, and NO‐NO. These are used to generate a set of transport collision integrals over the range 300–15 000 °K with an estimated uncertainty of about 5%.
