Concepts

Reading a 1H NMR Spectrum

1H NMR spectroscopy measures the magnetic environment of hydrogen atoms in a molecule. Each chemically distinct group of hydrogens produces a separate signal.

How to read the chart

The x-axis shows chemical shift in ppm (parts per million), increasing from right to left. The y-axis shows signal intensity - peaks point upward.

Three key pieces of information

Each NMR signal tells you three things: (1) chemical shift - what type of hydrogen, (2) splitting pattern - how many neighbors, (3) integration - how many hydrogens.
