Cross sections and rate coefficients for total and fine-structure resolved charge transfer in collisions of O+ with H and H+ with O are presented for collision energies between 0.1 meV/u and 10 MeV/u and temperatures between 10 and 107 K. The results are obtained utilizing new quantal and semiclassical molecular-orbital close-coupling, classical trajectory Monte Carlo, and continuum distorted wave calculations in conjunction with previous experimental and theoretical data. Applications to various astrophysical and atmospheric environments are discussed.
