In this worksheet, we will practice using NMR spectra to identify and distinguish between compounds with the same molecular formula.
Adjacent protons can act as magnets and affect the amount of radiation required for proton resonance in NMR. This interaction causes .
- Aincreased shielding, forcing the chemical shift to be lower
- Brapid relaxation and unreliable integration results
- Cdecreased shielding, forcing the chemical shift to be higher
- Dspin-spin coupling, resulting in peak splitting
