Final answer:

NMR spectroscopy allows you to determine if a protein contains an alpha helix.

Step-by-step explanation:

The method that allows you to determine if a protein contains an alpha helix is NMR spectroscopy.

NMR spectroscopy works by using the magnetic properties of atoms to determine the three-dimensional structure of proteins in aqueous solution. It can provide detailed information about the secondary structure of a protein, including the presence of alpha helices.
