Abstract:
The spectral properties of singlet-oxygen luminescence at the ${}^{1}\Delta_{g}\to{}^{3}\Sigma_{g}$ transition in the presence of rose Bengal as a photosensitizer are analyzed. The effect of iodine in solution in CCl$_4$ on the efficiency of singlet-oxygen generation and on the structure of singlet-oxygen luminescence is shown. The results of studies with tetrachloromethane are compared with the results obtained with other solvents.
