Results of the quantum biological study of an interaction of potent carcinogens such as 4-nitroquinoline 1-oxides and aromatic hydrocarbons with tissue components, especially with deoxyribonucleic acid (DNA), are presented and chemical carcinogenesis is discussed in connection with charge transfer phenomenon. An equation is derived to obtain the charge transfer quantity between two constituent molecules in the charge transfer complex, and distinct parallelism is found between the quantity of charge transfer and carcinogenic activity. From this result, it is suggested that the quantity of charge transfer is more important in the genesis of tumor than the charge transfer force. Summation of an alteration of base paring in Watson-Crick stereo-model of DNA resulting from the charge transfer between DNA and the carcinogens is deemed to be the cause of tumor.
