Analysis of the shape of the orienting potential, which constrains the preferred orientation of the effective axis of internal rotation of the tethered nitroxide, revealed the presence of two different conformations of the spin-label moiety. In order to explain these results, the quantum chemical procedure was utilized. The spin-label moiety in the polymer system was reduced to 4-acetamido-2,2,6,6-tetramethylpiperidine-l-yloxyl (II) (spin label plus tether). The molecule was subjected to a search for stable confonn-ers, which resulted in the two minima corresponding to the structures Da and nb." ... [Pg.160]
