The electron paramagnetic resonance (epr) spectra of the diarylmethylenes: diphenylmethylene, p-cyanodiphenylmethylene, p-methoxydiphenylmethylene, p, p'- dimethoxydiphenylmethylene, p, p'-dicyanodiphenylmethylene, p-cyano-p'- methoxydiphenylmethylene, have been studied. The zero-field splitting parameters have been determined. The signal intensity as a function of temperature (ca. 4-20 K) indicates ...
