N2 - Novel experimental values of collisional broadening and shifting coefficients for the Fermi triad of CO2 in mixture with methane at 296.0(2) K were determined from high resolution FTIR measurements. An empirical function for the broadening coefficients is obtained: γn(J′) = 0.0762(7) + 0.00320(4) · exp(− 0.039(3) · J′) /cm–1/atm, here J′ refers to the final state, n = 1, 2, 3 labels the Fermi components. Expanded uncertainties (2σ) for 38 out of 55 reported values are smaller than 0.5%. The absolute values of shift coefficients are about ten times smaller than the broadening, and the relative uncertainty is larger (4–5%).
