The behavior of subexcitation electrons in gaseous mixtures of O{sub 2} and N{sub 2} is studied by using the Spencer-Fano theory and its simplified continuous-slowing-down approximation. Because of its strong resonance around 2 eV, N{sub 2} is overwhelmingly dominant over O{sub 2} in energy-loss processes. Addition of N{sub 2} to O{sub 2}, even a few percent, causes significant changes in some yields of O{sub 2}. In particular, yields for electron attachment and rotational excitation for O{sub 2} show a strong nonlinearity as a function of composition, while all yields of N{sub 2} depend linearly on composition.
