Electron spin resonance absorption was detected in mesonaphthodianthrene and mesonaphthodianthrone. The spectra of both of these compounds consist of, at least, seven lines with a separation of 4.4 oersteds and the central line has a g-value of 2.0024 ± 0.0002. The growth of the central line by admission of air was observed in the case of the hydrocarbon. Some suggestions are presented as to the nature of the unpaired electrons in these compounds. The magnitude of the molar diamagnetic susceptibility of mesonaphthodianthrene, after correction for the paramagnetic contribution from the unpaired electrons, is discussed in relation to the molecular structure.
