Carbon monoxide

Energy levels, transition frequencies and Einstein A coefficients were taken from CDMS and JPL (However, see notes in the case of 13CO). The collisional rate coefficients are adopted from Yang et al. (2010) and includes energy levels up to J=40 for temperatures ranging from 2 K to 3000 K. These rate coefficients, for collisions with both para- and ortho-H2, use close-coupling and coupled-states approximation scattering calculations and the interaction potential of Jankowski and Szalewicz (2005).
