The electronic structure of some polyenes and aromatic molecules III—Bonds of fractional order by the pair method

Abstract Lennard-Jones and Turkevich in the preceding paper have investigated by the orbital method the nature of the binding in various aromatic molecules due to the mobile electrons. The purpose of the present paper is to make somewhat similar calculations by the pair method. The author has had the benefit of several discussions with Professor Lennard-Jones, and he is glad to take this opportunity of acknowledging them.
