本文测定了10个乙酰苯胺衍生物的^1H, ^1^3C NMR谱, 采用质子自旋去偶, 质子选择去偶, 质子偏共振去偶, 质子去偶的^1^3C DEPT和选择INEPT等技术对其谱线进行归属。系统地研究了围绕羰基碳氮键的受阻旋转, 确认了该类化合物在溶液中存在E和Z型构象体, 并探讨了各种取代基对形成异构体比例的影响。

decoupled, selective proton decoupled, proton off-resonance decoupled, DEPT and selective INEPT techniques. The restricted rotation about the carbon-nitrogen bonds of the amide group of acetanilides was studied. The mol. structure of acetanilides in solution can be described in terms of an equilibrium between E- and Z-forms. The effect of various substituents on conformation is discussed.
