Electron Paramagnetic Resonance Spectra of Carbonate Centers in Natural Apatites

  • L. G. Gilinskaya


The EPR spectra of carbonate centers in apatites of different compositions are measured in the range 77–290 K. The results indicate that the F : OH ratio on the 63 axis and the state of constitutional water (H2O molecules) determine vibronic interactions in the CO2, CO3, and CO33− centers and the parameters of their EPR spectra. Depending on the molecular water and OH contents, the spectra of the carbonate centers are isotropic or anisotropic, due to the dynamic or static Jahn-Teller effect. Computer simulation is used to estimate the contributions of the centers to the EPR spectrum.
