Abstract

¹⁹F and ¹H NMR investigations have been carried out on three powder samples of CsCaF_3-xH_x composition (0 ≤ x ≤ 1.70), and on a single crystal of CsCaF₃. It appears that the spectra of ¹⁹F are consistent with a distortion of the Ca(F,H)₆ octahedra involving either lower symmetry or a random distribution of a c₄-maxis with respect to the crystallographic directions.
