第一个：To overcome signal overlap, NMR data were acquired in methanol-d 4 as well as a 1:1 mixture of methanol-d 4 /pyridine-d 5 . This simple strategy was particularly useful to connect the C16−C18 and C28−C30 positions
第二个：Deuterium shift experiments using methanol-d 3 showed no changes for C6, C10, C17, C21, C29, C33, C34, C35, and C36 indicating that these carbons were attached to nonprotonated oxygens.
有人了解过这两种方法么

请问你用过相关的方法么，有相关的文献么

用过混合溶剂。methanol-d 4 和pyridine-d 5可以互溶，后者是各向异性溶剂，对您的目的有用。

哦哦，谢谢您啦，还想再问您一下您了解methanol-d 3么

methanol-d3是常用的NMR氘代溶剂，甲醇-CH3的3个H原子被氘（D)取代。
