We observed a well resolved ESR spectrum of 2-<I>t</I>-butylaminotropone <I>N</I>-oxyl radical generated by the oxidation of the corresponding amine with perbenzoic acid, and assigned the values of hyperfine coupling constants of protons in the tropone ring by a comparison with the ESR spectra of deuterium substituted 2-<I>t</I>-butylaminotropone <I>N</I>-oxyl radicals: <I>a</I><SUB>N</SUB>=12.7 gauss, <I>a</I><SUB>H</SUB><SUP>3</SUP>=<I>a</I><SUB>H</SUB><SUP>5</SUP>=<I>a</I><SUB>H</SUB><SUP>7</SUP>=1.86 gauss and <I>a</I><SUB>H</SUB><SUP>4</SUP>=<I>a</I><SUB>H</SUB><SUP>6</SUP>=0.93 gauss for protons on tropone ring.
