| Popis: | The anisotropic EPR spectrum of C 10 H 8 FeC 5 undergoes Jahn-Teller effect induced transition to the isotropic spectrum at 123 K in the solid phase. Iron atom tunnelling between the naphthalene benzene nuclei may serve as a model of motion averaging g -factor anisotropy. The model is confirmed by studies of the α-MeC 10 H 7 FeC 5 H 5 and β-FC 10 H 7 FeC 5 H 5 EPR spectra. The latter two compounds show splitting of the g | signals into two components corresponding to dissimilar isomers at temperatures above 77 K. The isomers differ in the mode of iron bonding with the substituted and unsubstituted naphthalene nuclei. |
