Descripción general

Magnesium sulfate heptahydrate is the hydrated salt of magnesium. The spin-Hamiltonian parameters of the (Cu(H2O)6)2+ complex in magnesium sulfate heptahydrate have been determined by electron spin resonance (ESR) spectral studies.[1] Raman spectra of 10 hydrated and anhydrous forms of magnesium sulfates have been reported. Their crystal structure and space groups have been evaluated by Raman and XRD (X-ray diffraction) studies.[2]
