Structure Determination Using NMR
There are three basic aspects of an NMR spectrum that help chemists determine the chemical structure a substance:
- Chemical Shifts - peak frequencies (Hz or PPM)
- Scalar Couplings - peak splitting patterns
- Intensities - area under a peak or set of peaks
Move the mouse over the hydrogen molecules in the chemical formulae below to highlight their contribution to the associated NMR spectrum.
