Internal field correction for infrared band intensity measured in solutions

摘要

The Polo and Wilson equation has been widely used to eliminate the effect of the internal electric field from the observed infrared absorption intensities in the condensed phase. However, the validity of this equation for solution states has not been confirmed yet. This paper gives a new equation for the internal electric field correction in solution states according to the two kinds of molecular models. The equation obtained is identical to that of Polo and Wilson to the limit of pure liquid.
