Brief Principles of Symmetry-Based Recoupling in Solid-State NMR

In session 28 held on 25th May 2021, Prof. Malcolm Levitt gave a talk on the principles of symmetry-based recoupling in solid-state nuclear magnetic resonance (NMR) spectroscopy, via Zoom. The video was recorded live during the presentation and serves as an educative lecture.

Prof. Levitt obtained his PhD from Oxford University in 1981, under the supervision of Prof. Ray Freeman. He performed postdoctoral research with Profs. Shimon Vega in Israel and Richard Ernst at the ETH in Zürich (who received the Nobel Prize in Chemistry in 1991). He was then on the research staff at the Francis Bitter Magnet Laboratory at MIT, Boston, USA, for 4 years. He moved back to England as a Royal Society Research Fellow at the Centre for Superconductivity in Cambridge, before becoming a lecturer at the University of Stockholm, Sweden, where he was made a full professor in 1997. He moved back to England to take up a Professorship in Physical Chemistry at the University of Southampton in April 2001.

Abstract:

- high-resolution solid-state NMR requires removal of anisotropic spin interactions; useful information is conveyed by anisotropic spin interactions; having the cake while eating it.

- rotational symmetries of the spin interactions; space, spin and field signatures

- magic-angle spinning and spatial averaging

- multiple-pulse NMR and spin averaging

- combined spin/spatial/time symmetries

- symmetry-based selection rules and space/spin selection diagrams

- C-sequences

- R-sequences

- some examples
