Abstract

Electron spin echo modulation effects have been investigated in trans bis(2,2,5,5-tetramethyl-3-imidazoline-3-oxide-1-oxyl-4-il) ethylene biradicals involving 14N or 15N nuclei in different positions. The modulation frequencies are shown to be the nitrogen nuclear transition frequencies in radical fragments at mS = 0 of a triplet electronic spin. Quadrupole splitting parameters for these nitrogen nuclei have been determined.
