In the infrared region, an expression for the mean absorption intensity has been obtained using the Elsasser model based only on the assumption of pressure broadening. Around atmospheric pressure, however, a better interpretation of the empirical results has been found by introducing a new effect of splitting due to the pressure of the degenerate vibrational-rotational levels.
