ABSTRACT
In Chapter 6 we have discussed electron spin resonance (ESR)
lineshapes for nitroxide radicals containing 14N and 15N isotopes.
For this purpose we have considered a two-spin system consisting
of an electron spin and a nuclear spin of 15N or 14N. In this chapter
we shall go a step further and enquire how the isotropic hyperfine
coupling between the electron spin and the nitrogen spin affects
proton (1H) spin relaxation when the paramagnetic species are
dissolved in proton containing liquids.
