dc.description.abstractThe infrared $(4000-33 cm^{-1})$ and laser Raman spectra have been obtained for the following apatites: fluorapatite $Ca_{10}(PO_{4})_{6}F_{2}$, chlorapatite $Ca_{10}(PO_{4})_{6})Cl_{2}$, hydroxyapatite $Ca_{10}(PO_{4})_{6})(OH)_{2}$, pyromorphite $Pb_{10}(PO_{4})_{6}Cl_{2}$, mimetite $Pb_{10}(AsO_{4})_{6}Cl_{2}$ and vanadinite $Pb_{10}(VO_{4})_{6}Cl_{2}$. Simple site group theory, which has been used by earlier workers investigating the infrared spectra of these solids, does not satisfactorily explain the differences observed between infrared and Raman spectra. However, factor group analysis based upon six distorted tetrahedral groups per unit cell will account for these variations. The comparison of the infrared and Raman spectra has also led to the reassignment of the $\sigma_{2}$-modes to higher frequencies. These results are consistent with those predicted by normal coordinate analysis using a Urey-Bradley force field.en_US
