本文对 ABC 三自旋质子磁共振谱的标划归属提出了一个新的方法.一、前言ABC 三自旋质子磁共振光谱的精确分析,文献上作过不少报导,提供了各种的求解方法.在各种精确求解方法中,均先对实验谱线按照重复间隔规则,或再结合谱线强度进行标划归属,然后求出能阶(本征值),进而求出体系的偶合常数和化学位移.Castellano 与 Waugh 从体系的核自旋哈密顿(H)矩阵出发,已经证明对任何 ABC 体系
In this paper, we propose a new method for the assignment of ABC tri-spin proton magnetic resonance spectroscopy to spectra.First, the precise analysis of ABC tri-spin proton magnetic resonance spectroscopy has been reported in the literature and provides various solutions Method.In all kinds of exact solution methods, the experimental spectral lines are firstly assigned according to the rule of repeated intervals or the recombination spectral line intensity, then the energy level (eigenvalue) is obtained, and then the coupling constant of the system And chemical shifts .Castellano and Waugh, starting from the system’s nuclear spin Hamiltonian (H) matrix, have demonstrated that for any ABC system
