This lecture offers a step-by-step strategy for interpreting an NMR spectrum. It requires determining what pieces are present, figuring out how they go together, and then confirming the structure. Step 1 is to start with the IR spectrum to identify functional groups, especially carbonyls and alcohols. Step 2 is to analyze the molecular formula for unsaturation. Step 3 is to draw pieces of the molecule (CH₃ group, aromatic ring), and then step 4 is to confirm them. Then, put the pieces together by considering which groups are electron rich or deficient, and lastly, check the answer. The lecture ends with multiple Carbon-13 and Hydrogen-1 NMR examples and practice problems.
