Questions & Step-by-Step Solutions

What does a splitting pattern in an NMR spectrum indicate?
  • Step 1: Understand that NMR stands for Nuclear Magnetic Resonance, a technique used to study molecules.
  • Step 2: In an NMR spectrum, each peak represents a specific type of hydrogen atom (proton) in a molecule.
  • Step 3: The splitting pattern refers to how many smaller peaks appear around a main peak.
  • Step 4: This splitting occurs because neighboring protons (hydrogens) affect the magnetic field of the observed proton.
  • Step 5: The number of neighboring protons can be determined by counting the number of smaller peaks around the main peak.
  • Step 6: The general rule is that if a proton has 'n' neighboring protons, it will split into 'n + 1' peaks.
