Abstract
The rate constants for energy transfer have been measured by flash spectroscopic techniques. These results show that 1,3-cyclohexadiene undergoes a nonvertical transition when low energy sensitizers are used.
The quantum yields for the high energy sensitized dimerization of 1,3-cyclohexadiene are consistant with the simple mechanism proposed.
The use of 1,2-benzanthracene, a low energy sensitizer, to sensitize the dimerization of 1,3-cyclohexadiene has been studied in detail. The results show that in addition to energy transfer from donor to acceptor, other steps such as reversible energy transfer, adduct formation, singlet quenching of aromatic hydrocarbons by dienes and sensitizer-sensitizer interactions are important.
