Abstract: The interaction of singlet oxygen with the olefins 2, 5-dimethyl-2, 4-hexadiene (DMHD) and 1-methyl-2-phenylindene (MPI) leads to both reaction and quenching. Although the initial interaction with singlet oxygen is nearly independent of solvent and temperature, the relative amount of quenching depends on solvent in the case of DMHD and on both solvent and temperature in the case of MPI. The increased reaction rate for ...
