Notes:
The combination of high-performance liquid chromatography (HPLC) and ESR spectrometry was used to isolate the free radicals produced by the reaction of a Grignard reagent with 15 substituted α-Phenyl-N-tert-butylnitrone. Long-range hyperfine splitting constants (hfsc) were obtained by the resolution enhancement method. Linear correlation studies between hfsc and Hammett σp constants are reported. Dual-parameter correlations using σR and σI were also studied. The mass spectra for the HPLC-isolated spin adducts and their fragmentation patterns are reported.
