NMR Chemical Shifts Beyond Numbers
During the 65th session of the Global NMR Discussion Meetings held on April 4th, 2023 via Zoom, Prof. Christophe Copéret gave a talk on the topic "NMR Chemical shifts Beyond Numbers: From Understanding Electronic Structures to Reactivity Descriptor". The recording serves as a tutorial.
Abstract: NMR chemical shift is successfully used to identify the structure of molecules (and materials) making NMR an invaluable tool of characterisation. Because of its power to elucidate molecular structure, NMR interpretation is taught at an early stage, often in laboratory courses, even before one understands the fundamentals of spectroscopy and their selection rules. This lecture will concentrate on developing a detailed understanding of the origin of NMR chemical shift, and show how it can be used to reconstruct the electronic structure of molecules, in particular organometallic intermediates. This lecture will illustrate why the symmetry of the angular momentum operator makes NMR a privilege spectroscopic descriptor of reactivity.
Christophe Copéret is a Professor of Chemistry and Head of the Laboratory of Inorganic Chemistry at ETH Zürich, Switzerland.
