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( 3 F) and O( 3 P) atoms is dominated by an approach along the C 3 Δ potential energy curve, accompanied by spontaneous emission into the X 3 Δ 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 cm 3 s −1 , respectively.
