The proton magnetic resonance spectra of single crystals of Na 2Zn(SO 4) 2路4H 2O have been investigated and the orientations of the water molecules have been determined. Using the heavy atom structure determined by X-rays a system of hydrogen bonds between water and sulphate oxygens has ...

Ferroelastic and ferroelectric domain structure in lithium ammonium sulphate and its deuterated analogue are observed with the scanning electron microscope. Samples are cutted perpendicularly to the three main crystallographic directions. The pictures of all these faces in ferroelectric and ferroelastic phases...
THE crystal structure of gypsum, CaSO42H2O, was determined by Wooster in 1936 (ref. 1) from X-ray diffraction measurements, and further refined by Atoji and Rundle in 1958 (ref. 2) from neutron diffraction data. This latter work fixed the position of the hydrogen atoms, which was not p...
Results Structure and Morphology. As might be expected, the structure of MCNC-SA is very similar to that of the MCNC from which it is derived15. The particle size ranges (Fig. 1a) and Brauner-Emmett-Teller (BET) surface areas of MCNC-SA are estimated to be 2–200 μ m ...
Paramagnetic Resonance in Diluted Copper Salts. I. Hyperfine Structure in Diluted Copper Tutton Salts The principal values of the g-tensor and the hyperfine structure (due to interactions with the magnetic dipole and electric quadrupole moments of the stable copper isotopes) have been determined in ...
