ROO自由基（R=正丁基，枯基）的ESR谱含有氧富集在同位素170，已被检测到在-100。170个超精细常数分别为21.8± 0.1G和16.4± 0.1G。从170个流形上线宽的变化，可以将这两个超精细常数分别分配给末端和内部氧核，并得出结论，末端氧的自旋密度大约是内部氧的两倍。
Esrspectra of ROO radicals (R= r-butyl, cumyl) containing oxygen enriched in the isotope 170, have been detected at—100. The 170 hyperfine constants were 21.8±0.1 G and 16.4±0.1 G. From the variation in the line widths across the 170 manifolds it was possible to assign these two hyperfine constants to the terminal and inner oxygen nuclei, respectively, and to conclude that the spin density on the terminal oxygen was approxi-mately twice that on the inner.
