Conclusions
-
1.
The observed change, with change in temperature, in the components of the tensor of the hyperfine interaction and in the relative intensity of the corresponding ESR lines is due to the anisotropic vibrational motion.
-
2.
The observed anisotropy of the motion makes it possible to relate the values of the magnetic parameters to the molecular axes of the complex in nonoriented systems.
