After a short reminder of main line profile models currently used for extracting the collisional parameters from experimentally observed line shapes, some new aspects and applications of semi‐classical theories of collisional line broadening and shifting of molecular gases are reviewed. A simplified semi‐empirical approach proposed in the literature for water vapor and carbon dioxide molecules is also mentioned and illustrated for molecular systems with weaker interactions. For the presented molecular pairs and temperature ranges, the calculated collisional line widths and shifts compare favorably with available experimental data.
