| Abstract: | The infrared spectra of orthoarsenates with apatite structure, of the formulaM
5(AsO4)3
X (M=Ca, Sr, Ba, Pb andX=F, Cl,Br) are measured and interpreted on the basis of a site-symmetry analysis. The influence of the different cations on the internal vibrations of the AsO3
4-ions is discussed. |
