the pattern is uncertain and it is not observed for all dinuclear Mn(II) centers [37].
Spectra have been identified as arising from dimer systems by their dissimilarity to the
spectra of monomeric analogues, their similarity to other dimer spectra, or more
definitively, by their characteristic eleven-line hyperfine pattern with a splitting of
4.0-4.7mT [37]. The sextet pattern at g=l.995 of 20 is_typical for octahedral
manganese(II) environment. The magnitude of the hyperfine splitting, 263 MHz (94.2
G), is consistent with octahedral
