## Abstract Efficient pulse sequences for measuring ^1^H–^1^H coupling constants (__J__~HH~) in strongly coupled spin systems, named selective __J__‐resolved‐HMQC‐1 and ‐2, have been developed. In the strongly coupled spin systems such as ‐CH~2~‐CH~A~(OH)‐CH~B~(OH)‐CH~2~‐, measurements of ^3^__J__~
