NMR relies on the magnetic properties of atomic nuclei. When placed in a magnetic field, nuclei such as hydrogen-1 or carbon-13 resonate at specific frequencies. By measuring these resonances, NMR provides detailed insights into molecular structure, dynamics, and interactions.
EPR, on the other hand, focuses on unpaired electrons. It measures the resonance frequencies of these electrons in a magnetic field, providing information about the local environment of paramagnetic species. This technique is particularly useful for studying transition metal complexes and free radicals.
