## Abstract A new pulse sequence for determining scalar long range C,H spin couplings in small organic molecules is proposed. It is based on the combination of a selective __J__โresolved spectrum with a selective HMBC and displays the longโrange spin couplings of one chosen carbon atom in the indir
## Abstract A pulse sequence (SELRESOLV) for the protonโdetected determination of longโrange C,H coupling constants is described. The 2D __J__(HH) resolved experiment with selective ^13^C excitation separates __J__(HH) from __J__(CH) couplings. Application is demonstrated using crotonaldehyde and ฮฒ
