The optical absorption spectra of the Mn<SUP>2+</SUP> ion in MnM(edta)·6H<SUB>2</SUB>O (M=Zn, Cu, Ni, and Co) were measured at low temperature. Fine structural bands corresponding to the <SUP>6</SUP>A<SUB>1g</SUB>→<SUP>4</SUP>T<SUB>2g</SUB> (D) and <SUP>6</SUP>A<SUB>1g</SUB>→<SUP>4</SUP>A<SUB>1g</SUB>, <SUP>4</SUP>E<SUB>g</SUB> (G) transitions were found. The fine structure corresponding to the <SUP>6</SUP>A<SUB>1g</SUB>→<SUP>4</SUP>A<SUB>1g</SUB>, <SUP>4</SUP>E<SUB>g</SUB> (G) transition in the Zn compound were analyzed with the ligand field theory and the assignment of the absorption peaks was performed. Although the spectra of the Zn, Cu, and Co compounds are similar, those of the Ni compounds show significant broadening, which is possibly due to the energy transfer caused by the overlapping of the absorption bands of the Ni<SUP>2+</SUP> and Mn<SUP>2+</SUP> ions.
