Absorption spectra of OMZ (), iodine, 0.20 mg mL−1 in 1,2-dichloroethane (), DDQ, 0.40 mg mL−1 in acetonitrile (), OMZ-iodine complex in 1,2-dichloroethane at 25 2°C (), and OMZ-DDQ complex in acetonitrile at (5). Concentrations of OMZ were 30.00, 1.50, and for the absorption spectra numbers (), (), and (), respectively.
