Nuclear Magnetic Resonance (NMR) was first experimentally observed in late ... Spin-spin coupling allows one to identify connections between atoms on a molecule, through the bonds that connect them.

When fewer bonds are formed, unusual compounds such ... Electron paramagnetic resonance (EPR) and electron–nuclear double resonance (ENDOR) spectroscopies revealed that the compound contains ...
