Recent calculations of radiative charge transfer and radiative association rate coefficients are presented. In the case of C and He+, both in their ground states, radiative charge transfer is found to be large compared to direct charge transfer at thermal and lower energies [1]. In the case of C and H+ interacting via triplet molecular potentials, the rate coefficients for radiative association are found to be about 100 times larger than the (well-studied) values for radiative association via singlet molecular potentials [2]. New calculations of the radiative association rate coefficients for Si and O are discussed [3].
