| Abstract: The powder and magic-angle spinning (MAS) experiments on 171Yb in AYbI3(A:K,Rb, Cs) are reported. The NMR parameters,such as the principal components of the chemical shielding tensor(δave-,δ∥,δ⊥),the parallel and perpendicular components of longitudinal times(T1,T1∥,T1⊥) are determined in solid state and the transverse relaxation time was obtained from the natural line width.The local symmetry of Yb was discussed according to the spectra shape. |
| Keywords: 171Yb powder and magnic-angle spinning nuclear magnetic resonance relaxation time relaxation anisotropy chemical shielding tensor ytterbium compound AYbI3(A:K Rb Cs) local symmetry of Yb |
