Nuclear magnetic resonance (NMR) measurement of 1JCC coupling by two‐dimensional (2D) INADEQUATE (incredible natural abundance double quantum transfer experiment), which is a special case of double‐quantum (DQ) spectroscopy that offers unambiguous determination of 13C–13C spin–spin connectivities through the DQ transitions of the spin system, is especially suited to solving structures rich in quaternary carbons and poor in hydrogen content (Crews rule).

INADEQUATE NMR技术的应用,用于直接追踪天然产物的碳骨架。

二维(2D)INADEQUATE(不可思议的自然丰度双量子转移实验)对1 J CC耦合的核磁共振(NMR)测量,这是双量子(DQ)光谱学的特例,它可以确定13 C –通过自旋系统的DQ跃迁实现13 C自旋-自旋连通性,特别适用于求解富含季碳且氢含量较低的结构(克鲁斯法则)。
