Duzor et al. The reader is referred to Fig. The Cooper-Zare formula is strictly applicable to atomic transitions only, but similar approaches taking rotational motion into account have been developed for diatomics. In the absence of resolved rotational structure, the original Cooper-Zare formula has been used to describe photodetachment of molecular anions, including O2  and S2  . These applications rely on the approximate description of the detachment orbitals in these diatomics using a single atomic-like function with l = 2. To this end, Fig. (b) includes a model curve calculated using
