Abstract
An enhancement of infrared absorption bands is shown to be inherent in charge‐transfer theory due to change in vertical ionization energy or change in vertical electron affinity during the course of molecular vibration. A semiquantitative calculation of the intensity enhancement of the symmetric ring stretching vibrational mode of benzene in the benzene‐iodine complex agrees well with the experimentally observed value. This result shows that previous investigators' assumptions of charge‐transfer complex asymmetry, based on observed infrared absorption bands may not be valid.Keywords
