Abstract
Isotropic splitting constants for 14N, 15N, 13C, and 17O nuclei present in natural abundance in di‐t‐butyl nitroxide have been measured by electron spin resonance, using benzene solutions at room temperature. The proton hyperfine structure was not resolved, but was estimated from best‐fitting computer‐simulated spectra. Comparison of computer‐simulated single‐ and double‐substitution 13C satellites with the experimental satellites indicates that only six of the eight positions contribute to these satellites.
