This work outlines a technique to obtain transport collision integrals within the state to state (StS) framework, from potential energy surfaces. This method is used to compute state-resolved collisional transport quantities for the O+O2 system, based on the Varandas and Pais potential energy surface (PES).1 The potential governing the interaction of O and O2 at different levels of vibrational excitation is extracted, and scattering angles are computed for each case. The scattering angles are then used to compute the transport cross-sections from which the StS O+O2 collision integrals may be obtained. The relative orientation between the atom and molecule is assumed to be fixed during a collision event, and collision integrals are averaged over all possible orientations. This work presents the StS diffusion cross-section as a function of relative translational energy. It is found that the scattering angles change significantly with vibrational excitation of O2. The nature of the variation is also influenced by the relative translational energy of the colliding particles.
