Rate coefficients for the radiative association of titanium and oxygen atoms to form the titanium monoxide (TiO) molecule are estimated. The radiative association of Ti(3F) and O(3P) atoms is dominated by an approach along the C3Δ potential energy curve, accompanied by spontaneous emission into the X3Δ ground state of TiO. For temperatures ranging from 300–14 000 K, the total rate coefficients are found to vary from 4.76 × 10−17 to 9.96 × 10−17 cm3 s−1, respectively.
