• The nuclear quadrupole resonance(NQR) of <SUP>35</SUP>Cl in KClO<SUB>3</SUB>, AgClO<SUB>3</SUB>, Ba(ClO<SUB>3</SUB>)<SUB>2</SUB>·H<SUB>2</SUB>O, and Cu(ClO<SUB>3</SUB>)<SUB>2</SUB>·6H<SUB>2</SUB>O at room temperature has been measured by using a spectrometer system capable of reproducing with fidelity the line shape. The line-shape parameters were determined from the observed spectrum. All the line shapes of the four chlorates are of an intermediate character between Gaussian and Lorentzian. The line-width in K and Ag salts seems to originate from the inhomogeneity of the electric-field gradient, itself a result of the imperfection of the crystal. In Ba salt, it was found that the line-width is determined by the magnetic dipole-dipole interaction between chlorine and protons in the water of crystallization. The Lorentzian is the superior component of the line shape in Gu salt. This is explained in terms of the anharmonicity of the torsional oscillation of the ClO<SUB>3</SUB><SUP>−</SUP> group.
