本文研究了丙酮溶液中配合物的平衡和结构。建立了一套计算机程序。通过化学位移数值的分析说明在溶液中主要存在两种平衡,并确定了平衡常数k_(11)=2.95×10~2l/mol,k_(1)6.1l/mol以及冠醚络合物的极限化学位移D_(11)~((H))=350Hz,D_(11)~((C))=-290Hz,D_2~((H))=1300Hz,D~((C))=-1600Hz。确认位移机制是电子磁矩和共振核的核磁矩通过空间直接偶极—偶极相互作用。
This paper studies the equilibrium and structure of the complexes in acetone solution. Set up a set of computer programs. The analysis of chemical shift values shows that there are mainly two kinds of equilibrium in the solution, and the equilibrium constants k_ (11) = 2.95 × 10 ~ 2l / mol, k_ (1) 6.1l / mol and the crown ether complex The chemical shift D 11 ~ H = 350Hz D_ 11 ~ C ~ = 290Hz, D_2 ~ (H) = 1300Hz, D ~ (C) = - 1600Hz. It is confirmed that the displacement mechanism is the electron magnetic moment and the nuclear magnetic moment of the resonance nucleus passes through the space direct dipole-dipole interaction.
