Abstract

The behaviour of four stable β-phosphorylated aminoxyl radicals of the pyrrolidinoxyl series has been studied by EPR spectroscopy in the presence of dimyristoyl-phosphatidylcholine (DMPC) unilamellar liposomes. The affinity of these compounds for the liposome structure was found to be more or less high depending on their hydrophobicity. In each case, computer simulations of experimental EPR spectra permitted the determination of the hyperfine coupling constants of the radical inserted in the phospholipid bilayer.
