Abstract

The paper presents an extensive study of the solvent effect upon the intensity of ir absorption bands. Because of the special importance of the (X—H) bonds (X=C, O, H), this study is restricted to the (N—H) and the (O—H) bonds of diphenylamine and α-naphthol, respectively. An easy way to calculate the integrated intensity directly from the record chart, saving much time and effort and avoiding a source of appreciable error, has been developed. The determination of the intensity in the gas phase (<i>A</i>_<i>g</i>) is difficult. An extrapolation method for determining (<i>A</i>_<i>g</i>) is presented. The values found are: <i>A_g</i> (N—H) = 21.6 × 10⁻⁸ }abs. units <i>A_g</i> (O—H) = 32.5 × 10⁻⁸ }abs. units It is also found that the absolute solvent interactions play an important role in the intensity variation.
