| 摘 要： | La(Ⅲ), Y(Ⅲ) complexes with diglycol aldehyde bis-arginine (H_2DAAR) and tetraglycol aldehyde bislysine (H_2TALY) Schiff bases were synthesized. They were characterized and formulated as La(H_2DAAR) (NO_3)_3·6H_2O and Y (H_2TALY)(NO_3)_3·5H_2O separately by elemental analyses. The obtained complexes were investigated in detail by high resolution solid state (HRSS) ~(13)C NMR using cross polarization, magic angle spinning (CPMAS), and total suppression of sidebands (TOSS)techniques. The results are supported by the liquid state 2D-~1H-~(13)C COSY NMR spectra. Some new information about the splitting peaks of ~(13)C for—CH=N—group and alkene carbon bands, etc. in HRSS ~(13)C NMR spectra are given.
