NMR Spectroscopy (HL) part 1/2

What is the primary purpose of NMR spectroscopy?

• To measure the color of a compound

• To determine the structure of molecules

• To identify the taste of chemicals

• To calculate the weight of atoms

Which isotope is commonly used in NMR spectroscopy?

How do protons behave in a magnetic field during NMR?

• They stop moving

• They disappear

• They align and spin like small magnets

• They change color

What does the area under a peak in an NMR spectrum represent?

• The weight of the molecule

• The number of protons in that environment

• The speed of the reaction
