Absorption in the 1–0 CO band wing broadened by He at different temperatures is regarded within the asymptotic line wing theory. It presents absorption as a sum of the absorption coefficients of individual line with a special shape at far distances from the line center. The line shape parameters pertaining to quantum and classical interaction potentials are found as a result of fitting to the experimental absorption data in the 1–0 CO band wing and the temperature dependence of the second virial coefficient.
