Abstract The formation and destruction of excited rare‐gas dimers have been studied using resonance optical excitation of high‐pressure gas mixtures containing Kr. From an analysis of the resulting emission, 19 reaction rate coefficients have been inferred. It is concluded that atom–atom interchange processes play a major role in rare‐gas eximer formation, and that stepwise relaxation down the eximer vibrational ladder is less important than multistep relaxation due to atom–atom exchange in the excited eximer.
