Description

Proton magnetic relaxation measurements carried out for [Mg(H2O)XL6](CLO4)2 revealed two processes responsible for T1 vs temperature dependence: one connected with H2O 180deg flips about the symmetry axes and second connected with a tumbling of the complex cation. Quasielastic neutron scattering measurements gave another evidence of H2O 180deg flips. The reorientational corelation times, which in the 273 K - 325 K region are of the order of picoseconds, as derived from NMR coincide perfectly well with those derived from QNS. (author)
