: In a strong external magnetic field, these nuclei align either with ( state ) or against ( state ) the field.
: Nuclei with an odd number of protons or neutrons (like ) behave like tiny magnets. Basic 1H- and 13C-NMR Spectroscopy
: 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 : In a strong external magnetic field, these
