Rates of 1O2 (1Δg) production upon direct excitation of molecular oxygen by 1270 nm laser radiation in air-saturated alcohols and micellar aqueous dispersions

The absorbance and molar absorption coefficients of dioxygen were estimated from measurement of the oxygenation rates of 1,3-diphenylisobenzofuran in air-saturated alcohols and H2O-sodium dodecyl sulfate dispersions upon 1269 nm laser irradiation.
