Stephen, Chinnamma (1964) An investigation of the magnetic and other related properties of oxyanion salts of some univalent and bivalent cations in the solid state.
Full text access: Open
1. The magnetic mass susceptibilities have been measured in the solid state at room temperature for series of salts of uni and bivalent cations of chlorates, bromates, iodates, perchlorates, triorthophosphates, sulphates and thiosulphates. The molar volume for these salts have also been calculated by determining the density at 20°C. 2. The additivity relationships of molar susceptibilities were studied and compared with the additivity of molar volumes. The effect of coordination number change on the susceptibility has also been considered. 3. The theoretical susceptibility for the simple ions was calculated by Slater's method. The methods of Pascal and Pauling were used to calculate the ionic susceptibility of the XO3 and XO4 ions.The experimental ionic susceptibilities were compared with the theoretical ones and a marked bond shortening effect on the susceptibility was noted. 4. Infrared spectra of the XO3 and XO4 ions were recorded and the characteristic vibrational frequencies were studied. An attempt was made to calculate the force constants for these ions and a comparison was made of the spectroscopic data and the magnetic susceptibilities. Some interpretation in relation to the bond length has been attempted.
