Abstract
From the intensities of powder diffraction lines the positions of the deuterons in NCl have been determined at liquid nitrogen and room temperatures. The experimental results confirm at low temperature the space group and the tetrahedral structure of the ammonium ion with an separation 1.03A. At room temperature the space group persists. Neither free rotation nor disordered orientations of the ammonium ions have been observed. Details concerning deuteron vibrations are discussed.
