We present calculated rate coefficients for ro-vibrational transitions of CO in collisions with H atoms for a gas temperature range of 10 K ≤ T ≤ 3000 K, based on the recent three-dimensional ab initio H–CO interaction potential of Song et al. Rate coefficients for ro-vibrational v=1,j=0−30→v{sup ′}=0,j{sup ′} transitions were obtained from scattering cross sections previously computed with the close-coupling (CC) method by Song et al. Combining these with the rate coefficients for vibrational v=1−5→v{sup ′}
