Rate coefficients for radiative association of SO, SO⁺, and S₂are estimated. For temperatures ranging from 300 to 14,000 K, the direct radiative association rate coefficients are found to vary with temperature from 1.73x10^–19 to 7.29x10^–19 cm³/s and from 1.49x10^–21 to 3.70x10^–19 cm³/s for S₂and SO, respectively. The rate coefficients for formation through the inverse predissociation for S₂are found to vary from 3.59x10^–18 to 1.44x10^–20 cm³/s. For SO⁺, the direct rate coefficient varies rapidly with temperature from 3.62x10^–27 cm³/s at 2000 K to 2.34x10^–20 cm³/s at 14,000 K. The direct radiative association rate coefficients increase with the increase in temperature, but the inverse predissociation rate coefficients decrease with the increase in temperature.
