The calculations used vibrationally independent intermolecular interaction potentials. The variation of CO half-width coefficients with rotational quantum number Jr24 was computed and compared with measurements. The agreement between the theoretical broadening coefficients is better for pure CO rather than for theCO-H2 system.
