What are the key characteristics of the NMR spectrum of aspirin?

The key characteristics of the NMR spectrum of aspirin include distinct peaks representing different types of hydrogen atoms in the molecule, such as aromatic and aliphatic protons. The chemical shifts of these peaks can provide information about the chemical environment of the hydrogen atoms, helping to identify the structure of the compound. Additionally, the integration of the peaks can indicate the relative abundance of each type of hydrogen atom in the molecule.
