✦ Synopsis

The X-band ESR spectrum of the high-resolution amphiphilic spin probe perdeutero-di-1-butyl nitroxide (PDDTBN), partitioning in the lipid and water phase of lecithin iiposomes, shows all three resonances from each phase well resolved. We report the results obtained from model membrane partition studies also in the presence of a-tocopherol and discuss the advantages of using this probe with respect to using the more popular piperidine nitroxide TEMPO.

The high-field (i.e., 94 GHz) membrane EPR spectra of lipids spin labeled in their fatty acid chains have been simulated by using two limiting motional models. The aim was to identify the dynamic origin of the residual (g(xx) - g(yy)) anisotropy observed in the nonaxial EPR spectra of cholesterol-co
