| Abstract: | The photoacoustic spectra of Co(H2EDTA)·3H20, Ca[Co(EDTA)H20]·4H20, Sr[Co(HEDTA)H20]2·4H20, Ba[Co(HEDTA)H20]2·4H20 complexes crystal are determined in the region of 300–800nm. In these spectra, the separations of absorption bands observed at 510nm and 650nm, the peak widths of 510nm band are variable in this series complexes. It is explained by the electron mutual effect, strength of ligand field and the symmetry of coordination group. The structure characters of these series complexes are also discussed. |
