摘要：

A method is proposed which allows a simple Pake doublet due only to the directly bonded C-H pair to be obtained by measuring the local field at the position adjacent to a C-13 nucleus under proton homonuclear decoupling. This approach allows precise determination of the C-H distance even in compounds with high proton density.
