Low-Field Magnetic Resonance for Detection and Other Applications
During the 89th session of the Global NMR Discussion Meetings held on October 8th, 2024 via Zoom, Dr. Adam Altenhof from the Los Alamos National Laboratory, New Mexico, US, gave a talk on the topic "Low-Field Magnetic Resonance for Detection and Other Applications". The recording serves as a tutorial
Abstract: Low-field NMR can offer better resolution than at high-field. Extremely homogeneous B0 fields and low susceptibility broadening results in signal lifetimes around 1 – 10’s of seconds. Earth’s field NMR and nuclear quadrupole resonance (NQR) both offer low cost, high portability, and applications for detection of illicit materials, including fentanyl.

Advances in the Computation of NMR Interactions in Materials
During the 81st session of the Global NMR Discussion Meetings held on February 27th, 2024 via Zoom, Dr. Sean T. Holmes from the Florida State University, United States, gave a talk on the topic "Advances in the computation of NMR interactions in materials". The recording serves as a tutorial.
Abstract: This lecture will discuss recent advances in the computation of NMR interactions in materials using density functional theory methods. These include methods for accounting for intermolecular interactions, the role of relativistic effects (especially for heavy atoms), and the choice of density functional approximation. Applications to elements from across the Periodic Table will be presented.
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.

The Basics of Ultra-Wideline Solid-State NMR Spectroscopy
During the 63rd session of the Global NMR Discussion Meetings held on March 7th, 2023 via Zoom, Prof. Robert W. Schurko gave a talk on the topic "The Basics of Ultra-Wideline Solid-State NMR Spectroscopy". The recording serves as a tutorial.
Abstract:
This tutorial will cover the basic concepts surrounding the acquisition of ultra-wideline solid-state NMR spectra, including the use of WURST pulses for direct excitation and broadband cross polarization, new methods for indirect detection, and applications to a wide range of nuclides from elements across the Periodic Table.
Robert Schurko is a Professor of Chemistry at Florida State University (FSU) and Director of the NMR and MRI User Program at the National High Magnetic Field Laboratory (MagLab) at FSU.

Abstract: NMR is a powerful atomic-level characterization technique but it suffers from an intrinsically poor sensitivity. Fast magic angle spinning and 1H detection in solids improve NMR sensitivity, but these are mainly applied to common spin-1/2 isotopes such as 13C, 15N, 29Si and 31P. Whereas, over 75% of the periodic table consists of unreceptive nuclei that are under-studied using NMR due to the lack of sensitive approaches. In this contribution 1H detection methods for low-gyromagnetic ratio nuclei, half-integer quadrupolar nuclei and high-Z spin-1/2 nuclei with high chemical shift anisotropy will be discussed. Practical considerations and some recent advances will be highlighted.
