Nuclear magnetic resonance is a powerful tool, especially for the identification of previously unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every organic chemist working in synthesis. Consequently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc., are well understood, and specialty methods have been developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelor's degree courses, with advanced methods integrated into master's degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectroscopy within the chemical community, it is remarkable that heteronuclear NMR is still regarded as something of a curiosity. Admittedly, most organic compounds contain only nitrogen.
