The nuclear magnetic resonance spectrum of ¹¹⁵In was recorded at room temperature in an InBi intermetallic compound From the observed spectrum the isotropic Knight shift (+0 18%), the axial component of the Knight shift (+0 02%) and the quadrupole coupling constant (6 6 Mc/s) at the site of the ¹¹⁵In nucleus have been measured. With the assumption of an ionic model, the quadrupole coupling constant at the site of the ¹¹⁵In nucleus in the compound has been calculated and compared with the observed one.
