要旨

A NMR 19F multiple pulse solid state high resolution experiment has been performed on α-SnF2. Four single crystals have been used with rotation axes, parallel to b, c*, a and 111 crystallographic directions respectively and eight shielding tensors have been determined. The assignment of these tensors to the eight magnetically inequivalent fluorines is made by considering the strongly axial properties of both the fluorine sites and the shielding tensors, and the large shielding anisotropy associated with the covalent character of the boudings. Wide line spectra are in agreement with the high resolution experiments.
