Raman spectra of single crystals of (NH4)2M(SO4)2·6 H2O whereM=Mg, Zn Ni or Co have been recorded using λ 2537 excitation. Interesting results concerning the substitution of the divalent atoms in the double sulphate lattice on the sulphate and ammonium frequencies are observed. The spectra of these double sulphates are discussed in the light of the known crystal structure details and in relation, to the spectra of the corresponding potassium double sulphates, reported recently by the author…

Paramagnetic defects in irradiated chromate doped “MASH” crystals
Abstract The X-irradiation of CrO2−14 doped Mg(NH4)2(SO4)2·6H2O revealed the formation of SO−3, NH+3 and CrO3−4 radicals. These defect centres are paramagnetic. The yield of NH+3 radical is greater

Deciphering the Crystal Structure of a Scarce 1D Polymeric Thorium Peroxo Sulfate.
TLDR
A combination of laboratory and synchrotron techniques allowed to solve the structure of Th(O2)(SO4)(H2O)2 compound which crystallizes in a new structure type in the space group Pna21 of the orthorhombic crystal system.
Libratory modes of water molecules in tutton salts
The existence of rocking, wagging and twisting librations of different types of water molecules in tutton salts has been established from their ir spectra. These bands have been identified, following
Impact of the particle mixing state on the hygroscopicity of internally mixed sodium chloride-ammonium sulfate single droplets: a theoretical and experimental study.
TLDR
It is demonstrated that NH4Cl, Na2SO4 and NH4NaSO4·2H2O are formed in recrystallized particles and coexist with NaCl and (NH4)2SO 4 and all these products are randomly distributed within the particles.
