In a previous paper, it was reported that the photodecomposition of menadione in aqueous solution was inhibited by the formation of the complex with various electron donors, and it was suggested that the complex formation among them might be attributed to charge-transfer force. The relationship between the structure of the complex in electronic aspect and the rate of stabilization were investigated by a molecular orbital method described in this paper. As a result, it was concluded that suppression of the photodecomposition of menadione with various electron donors is due to the charge transfer complex formation among them.
