1 Answer. Ernest Z. A compound exhibits as many signals as there are magnetic environments within the molecule.
What does 1H NMR tell?
H NMR is the go-to technique to help identify or confirm the structure of organic compounds or those that contain protons. A solution-state proton spectrum is relatively fast to acquire, compared with other nuclei, and a lot of information about the structure of a compound can be deduced from it.

- The four facets of 1H NMR spectroscopy:
- Summary of Steps in Beginner 1H NMR Interpretation:
- The relative areas of the signal-set integrals directly correlates the ratios of H's.
- ❑ N-1 Rule: N lines → N-1 neighbor H's (H's directly attached to carbons attached to the C-H.
- ❑ N+1 Rule: N neighbor H's → N+1 lines.
