Nuclear Magnetic Resonance (NMR) lab

Nuclear Magnetic Resonance (NMR) lab shown to Higher Chemistry pupils during the University of St. Andrew's 'Chemistry School'. Proton NMR is and C-13 NMR are both widely used in identifying the arrangment of hydrogen and carbon atoms in organic compounds. NMR works on the principle that certain isotopes such as hydrogen-1 and carbon-13 act like tiny magnets which align with or against a strong magnetic field. When subjected to a burst of electromagnetic radiation the atoms change alignment in the magnetic field. The energy of absorption by the nuclei varies depending on adjoining functional groups.
