Rotational energy levels of HCN (as used by Dumouchel et al, 2010; Sarrasin et al, 2010; Hernandez-Vera et al, 2014)

The following energy levels have been used in the Dumouchel et al, 2010; Sarrasin et al, 2010 calculations of the de-excitation of HCN by He. They were subsequently used for the HCN-H2 calculations of Hernandez-Vera et al, 2014.


The rotational, distortion constants come from "Microwave Spectra of Molecules of Astrophysical Interest, VI. Carbonyl Sulfide and Hydrogen Cyanide." A. G. Maki, J. Phys. Chem. Ref. Data 3, 221 (1974)
