Isotopologues of C2H2

12C21H2

Broadening coefficients for C2H2

Note: unless otherwise stated, the broadening coefficients for the principal (most abundant) isotopologue can be used for other isotopologues of the same molecule.

  • 12C2-1H2__H2.broad
    H2 line broadening parameters: a0-diet was produced by averaging values from J.S. Wilzewski et al JQSRT (2016); m0 and m2 diets produced in A. Sokolov et al. JQSRT (2025) using the CRBM method
