NMR chemical shift
A ¹H NMR spectrum: where signals appear, how big they are, and how they split.
Open the interactive simulation →How to use this simulation
- Choose a molecule.
- Tap a signal to zoom into its splitting pattern.
- Read the shift, integration, splitting and assignment.
What to notice
- Number of signals = number of H environments.
- n neighbouring H split a signal into n + 1 lines.
