In a recent study by R. Gamache and A. Laraia , the semiclassical Complex Robert‐Bonamy (CRB) formalism was used to calculate the half‐widths for the rotation band transitions of broadened by and air. The Robert‐Bonamy model of approximate trajectories (parabolic) derived from the isotropic intermolecular potential was used. In this work, the importance of considering realistic dynamics model is demonstrated by the comparison of the half‐widths obtained in  and new calculations using the (more realistic) Hamilton’s Equations model. The comparisons of this work with the previous one clearly demonstrate differences larger than the uncertainties desired by the spectroscopic and remote sensing communities.
