Role of NH4 and H2O in Tutton Salt (NH4)2M(SO4)2·6H2O (M=Fe and Zn) Single Crystals Studied by 1H and 14N NMR at High Temperatures
Journal of the Korean Magnetic Resonance Society
At high temperature, the roles of NH 4 and H 2 O in (NH 4 ) 2 Fe(SO 4 ) 2 ·6H 2 O and (NH 4 ) 2 Zn(SO 4 ) 2 ·6H 2 O single crystals were investigated using a pulse NMR spectrometer. Temperature was shown to have a significant influence, causing changes in the deformation of NH 4 and H 2 O. From the 1 H NMR and 14 N NMR spectrum, the forms of environment surrounding 14 N in NH 4 groups is more important than the loss of H 2 O groups. NMR studies indicate that NH 4 + ions in Tutton salts play andoi:10.6564/jkmrs.2017.21.2.067 fatcat:tsxmy4ln35e3hapxnwgjap4zn4
