In order to give a quantitative basis for the spin trapping technique, the spin trapping rate constants for the reactions between commonly-used spin traps and cyclohexyl radicals have been determined. The cyclohexyl radicals were generated by γ-irradiating cyclohexane solutions of the spin traps. The rate constants for nitrosobenzene, nitrosodurene, pentamethylnitrosobenzene, 2,4,6-tri-<I>t</I>-butylnitrosobenzene, and α-phenyl-<I>N</I>-<I>t</I>-butylnitrone at 299 K are 9×10<SUP>7</SUP>, 1.4×10<SUP>7</SUP>, 1.6×10<SUP>7</SUP>, 2.4×10<SUP>4</SUP>, and 8×10<SUP>3</SUP> mol<SUP>−1</SUP> dm<SUP>3</SUP> s<SUP>−1</SUP>, respectively. The results are qualitatively in accordance with previous data for <I>t</I>-butyl, 1-methyl-5-hexenyl radicals.
