What does the chemical shift in an NMR spectrum indicate?

Step 1: Understand that NMR stands for Nuclear Magnetic Resonance, a technique used to study molecules.
Step 2: Know that in NMR, we look at the signals produced by nuclei (like hydrogen or carbon) in a magnetic field.
Step 3: The position of these signals is called the chemical shift, measured in parts per million (ppm).
Step 4: Realize that the chemical shift tells us about the electronic environment around the nuclei.
Step 5: Different functional groups (like -OH, -NH2, -CH3) create different electronic environments, leading to different chemical shifts.
Step 6: By analyzing the chemical shifts, we can identify what functional groups are present in the molecule.
