In this worksheet, we will practice using 2D correlation spectra to determine which protons in a compound show significant spin–spin coupling.
In a COSY spectrum, the dark spots along the diagonal .
- Ado not give any structural identification because they are too intense to be deconvoluted
- Ballow distinctions to be made between heteronuclear coupling constants
- Cgive the most structural information because they differentiate between different hybridizations
- Ddo not yield structural information because they correspond to the same peak on each coordinate axis
