## Abstract Several different versions of the ^13^C‐detected ^13^C^1^H shift correlation sequence in phase sensitive mode with partial and full ^1^H^1^H decoupling are described and evaluated. As expected, they show sensitivity advantages over their absolute value analogues. Further, it is possib
## Three different two-dimensional "C-'H shift-correlation sequences which detect 'H chemical shifts and one bond '3C-'H[J(CH)I couplings in f, with full 'H-'H decoupling are described and evaluated. They are particularly useful for detecting small differences in 'J(CH) for nonquivalent methylene
