Abstract

Transport data can be calculated from collision integrals which are thermal averages of the transport cross sections. The limiting factor in this approach has been the lack of accurate potential energy surfaces describing the pairwise interactions of the gas constituents. The accuracy achievable by ab initio calculations has improved dramatically in the last few years[1]. Here and in the following paper[2] we present an overview of the results of our extensive theoretical investigations of the interactions among the components of Earth’s atmosphere. The primary objective of these studies is the determination of accurate interaction energies and the application of these interaction energies to establish a definitive data base that leads to reliable calculations of the transport properties for gases/plasmas formed from these components.
