本文分别用双共振选择性自旋去耦、双共振自旋搔动方法判定异植物醇中ABX体系耦合常数的相对符号为同号。阐明了用这两种双共振方法如何从实测谱图获得能级简图,进而判定ABX体系耦合常数相对符号巧妙的方法。
In this paper, double resonance selective spin decoupling and double resonance spin-on method were used to determine the relative symbols of ABX coupling constant in isophytol. It is illustrated how to get the energy level diagram from the measured spectra by these two kinds of double resonance methods and then to determine the ingenious method of the relative sign of the coupling constants of the ABX system.
