The first solid-state 171Yb nuclear magnetic resonance spectra.
The first powder and magic-angle spinning (MAS) experiments on 171Yb are reported. The divalent ytterbium compound RbYbI3 was studied by solid-state 171Yb nuclear magnetic resonance (NMR) and a powder spectrum of axial symmetry was obtained. The principal components of the chemical shielding tensor were determined as sigma 11 = sigma 22 = -62 ppm and sigma 33 = 124 ppm. An inversion-recovery experiment showed an anisotropic relaxation behavior with the parallel component relaxing faster than the perpendicular component (T1 perpendicular = 426 ms, T1 parallel = 298 ma). The natural line width of 800 Hz, which corresponds to an effective T2 of 0.4 ms, was obtained from the MAS spectrum.
