✦ Synopsis

Novel bands at 1073 and 1160 nm were detected in the spectrum of the photosensitized singlet oxygen luminescence in airsaturated solutions. The 1073 nm band was observed in carbon tetrachloride, freon 113 and hexafluorobenzene. The data suggest that it accompanies the { '4( v= 1) -%,( v=O)} transition in thermally activated singlet oxygen molecules. The 1160 nm band was detected in Ccl,. It probably corresponds to simultaneous vibronic transitions involving singlet oxygen and Cl atoms in solvent molecules.
