Experimental determination of the parameters of vibrational–rotational transitions in isotopic forms of CO2 molecules

Measurements were made of the absorption coefficients of carbon dioxide gas in the isotopically substituted forms ¹²C¹⁶O₂, ¹³C¹⁶O₂, and ¹²C¹⁸O₂. The Einstein coefficients, collisional line widths, and matrix elements of the dipole moments corresponding to the 00⁰1–(10⁰0, 02⁰0)_I,II transitions were calculated. The results were in good agreement with the available published data.
