Alignment of Three Nitroxide Radicals on the Same Face of a Helical Peptide Scaffold

摘要

A few investigations have been performed dealing with stable trmitroxide radicals, examined by EPR, to obtain information on the dependence of the electron spin-spin exchange interaction between unpaired electrons on 3D-structural parameters, temperature, and solvent polarity. These studies are a prerequisite for our understanding of the molecular magnetic phenomena and the structure and dynamics of biological systems in which poly-radicals are introduced as spin probes.
