High‐resolution NMR spectra of 3,6‐di‐ tert ‐butylquinone were recorded and analyzed for the first time in a wide range of temperatures. The spectra were transformed by paramagnetic additives of cobalt, nickel, and copper complexes synthesized on the basis of metal semiquinolates. Chloroform, dimethylsulfoxide, toluene, and acetone were used as solvents. It was shown that the spectra changed by paramagnetic additives can contain valuable information on the nature of a superfine interaction in paramagnetic complexes and on peculiarities of intramolecular dynamics inherent in these compounds.
