Abstract:

The effect of rotational interaction in the low energy dissociative recombination process of diatomic molecules has been explored for typical molecular ions (\(\)) which sample a large range of molecular masses. We show that rotation plays a role mainly for the indirect recombination process through bound Rydberg states, and for light molecules. When the direct process based on a strong electronic interaction is fast and dominating, rotational couplings can be safely neglected especially for heavier molecules like NO.
