Abstract

Abstract: 1, 8-Divinylnaphthalene has been irradiated in the presence of varying amounts of bromocyclopropane. The quantum yield for product formation was enhanced even though 1 &divinylnaphthalene fluorescence was quenched. This behavior indicates that the product was formed from the triplet excited state of 1 &divinylnaphthalene. Quantitative treatment of the enhancement and quenching data showed that the intersystem crossing quantum ...
