文摘The perturbation-theoretical treatment of electronic energy bands to molecular crystal has been put forward in a previous paper. Interatomic actions in molecular crystal are divided into two levels: the interatomic actions within the same molecule are strong, but those between different molecules are weak. The latter may be regarded as the perturbation of the former. This paper will give a concrete
