摘要: 以FT-NMR法直接测定了金属络合物MPy2Cl2、M(bi-py)Cl2、M(o-phen)Cl2(M为Cd、Sn、Hg)的111Cd、113Cd、117Sn、119Sn、199Hg NMR谱,考察了溶剂、浓度、温度对金属核化学位移的影响,讨论了谱图参数变化规律及一级同位素屏蔽效应。

Abstract: The 111Cd,113Cd,117Sn,119Sn,199Hg NMR spectra of metallic complexes MPy2M(bi-Py)Cl2, M(o-Phen)Cl2 (M=Cd, Sn, Hg) have been recorded directly using FT-NMR spectrometer. The influences of solvent, concentration and temperature on the chemical shifts of the spectra are investigated,The variations of the spectral parameters with the molecular structures as well as primary isotope shielding effects are discussed.
