大量涉及多原子分子离子的辐射缔合反应速率系数现在已经被计算出来，并被用于稠密星际云化学的离子-分子模型中。最近的证据表明，这些计算的速率系数可能是一个数量级太低，在许多情况下。对证据进行了审查和发展，并更新了计算的速率系数。此外，在10- 50 K范围内的每个反应速率系数的温度依赖性估计，如果这个信息以前没有出现在文献中。
A sizable number of radiative association reaction rate coefficients involving polyatomic molecular ions have now been calculated and utilized in ion-molecule models of the chemistry of dense interstellar clouds. Recent evidence suggests that these calculated rate coefficients may be an order of magnitude too low in many cases. The evidence is reviewed and developed and calculated rate coefficients are updated. In addition, the temperature dependence of each reaction rate coefficient in the 10--50 K range is estimated if this information has not previously appeared in the literature.
