Important Contributions:

Bates explained how electrons and positive ions recombine in ionosphere (with H. S. W. Massey). He gave theory of dissociative recombination and, much later, super-dissociative recombination. He devised Coulomb approximation for calculating absolute strengths of spectral lines (with A. Damgaard) in a "Science Citation Classic". Gave first study of photochemistry of atmospheric water vapour and explanation of Meinel hydroxyl bands in nightglow (with M. Nicolet). He also gave the theory of recombination of electrons and atomic positive ions by "collisional-radiative recombination" (with A. E. Kinston, W. R. P. McWhirter) in a "Science Citation Classic". Introduced the need for "translation factors" in quantal treatment of collisions involving charge transfer (with R. M. McCarroll). He gave explanations of stratospheric enrichments of heavy ozone and carbon dioxide.
