Abstract
In chloroform solution, naphthalene, anthracene, phenanthrene and pyrene have been found to show a number of absorption bands in the visible region in presence of acetylacetonates of copper and iron, but not of aluminium. The longest wavelength band in each case was found to correspond with the shortest singlet-triplet emission band in the phosphorescence spectra of the respective compound. By analogy with the absorption bands noticed with hydrocarbon solutions in presence of O2 and -NO by Evans, the absorption bands observed in the present case have been attributed to singlet-triplet absorption due to magnetic perturbation by metal chelates.
