请教汪老师? 汪老师:你好! 我的文章回审意见中有一段关于nmr 的,不是很清楚,特请教. changes in the methylene dihedrals of tame(my product) would typically be monitored by measuring changes in viscinal j-couplings and correlating with karplus curves. they might also be measured in a 1 h noesy experiment. 如何建立特定产物的j-coupling, dihedrals, karplus curves之间的关系? 谢谢! 查看更多
