the n.m.r. spectra of cis- and trans-1,2-diphenylcyclopentane and 3,4-diphenylcyclopentanone substituted in the para positions of both rings with methoxyl, methyl, and chloro substituents has shown that the previous explanation (1) of the effect of temperature on the n.m.r. spectra of 1,2-diphenylcyclopentane and 3,4-diphenylcyclopentanone (unsubstituted) was incorrect. The n.m.r. spectra provide no
检查顺式和反式 1,2-二苯基环戊烷和 3,4-二苯基环戊酮在两个环的对位被甲氧基、甲基和氯取代的核磁共振谱表明,先前对效应的解释 (1) 1,2-二苯基环戊烷和 3,4-二苯基环戊酮(未取代)的核磁共振谱上的温度不正确。核磁共振谱没有提供这些化合物的芳环旋转受到限制的证据。提供了另一种解释。 上述化合物的光谱与 meso- 和 dl-3 的光谱的比较,
