: After excitation, nuclei return to their base state, emitting signals that are detected and processed into a spectrum. Comparison: NMR Basic 1H- and 13C-NMR Spectroscopy
: Applying radiofrequency (RF) energy causes nuclei to "flip" between these states. The energy required depends on the electronic environment surrounding the nucleus, a phenomenon known as shielding . Basic 1H- and 13C-NMR Spectroscopy
: Nuclei with an odd number of protons or neutrons (like ) behave like tiny magnets. : After excitation, nuclei return to their base
is a powerful analytical technique used to determine the molecular structure of organic compounds by observing the magnetic properties of atomic nuclei. It primarily focuses on isotopes with a non-zero nuclear spin, such as (proton) and (carbon-13) . While NMR reveals the number and environment of hydrogen atoms, : After excitation
