| Citation | Pines has made profound theoretical and experimental contributions to nuclear magnetic resonance (NMR) spectroscopy, through which NMR has become an analytical tool for solid materials (catalysts, minerals, glasses, semiconductors, polymers ...). In a series of highly successful research collaborations, he developed and applied proton?enhanced NMR (launching the modern era of solid?state NMR in chemistry), multiple?quantum NMR (applied to structure determination of oriented molecules, clusters in condensed matter and spectroscopic filtering), zero?field Fourier?transform NMR (used to analyze disordered materials), dynamic?angle spinning and double rotation (enabling high resolution of quadrupolar nuclei such as oxygen?17), and optical?pumped NMR and MRI (enabling selective 'lighting?up' of NMR for molecules in solution and on surfaces), and he demonstrated geometric phases (adiabatic and non?adiabatic, Abelian and nonAbelian). For over twenty?five years, Pines has remained at the forefront of NMR in chemistry and physics; many of his developments have advanced biomedical research and led to commercial instrumentation. |
