The author tests the theoretical expressions for infrared band shapes, shows that varied factors affect band shapes, and explains that different investigators have tried to include those factors in the theory. The theory of infrared band shapes is very complex and relies on inexact figures, bringing the question of accuracy in doubt. Hence, at the present time, the problem is one of developing a theory which fits, as closely as possible, data which cannot be too accurately determined. The present work has been done as an experimental check on Gordon A. Gallup’s equations, which are similar to those created by Robert Herman and Richard F. Wallace. The results obtained do not give the expected verification. The author details the reasons for this disparity, including poor intensity measurements, the noise level in the recorder, the introduction of extrapolation of integrated intensities to zero pressure, and other factors.
