Abstract
The magnetic parameters of the ≡SiON(O·)CX3 nitroxides (X = H, D) grafted on an activated Aerosil surface were determined. The optimal geometry of the radicals was calculated and their rotational mobility was characterized. The activation energies to the rotation of radical fragments around various bonds were estimated.
