SUMMARY:Benjamin Tatman
DESCRIPTION:Beyond Exchange: Making Solid-State Relaxation Dispersion Less Coherent  \nThe measurement of Bloch-McConnell Relaxation Dispersion (BMRD) by NMR can provide useful insight into micro- and millisecond dynamics in biological systems. We recently demonstrated that the measurement of BMRD in the solid state has been plagued by three-spin recoupling conditions. The decoupling of these artefacts enables the measurement and quantification of BMRD down to previously inaccessible spin-lock frequencies\, even in fully protonated samples. Spurred on by these measurements\, we developed a new analytical framework for micro- to millisecond motional processes\, beyond the assumption of n-site exchange common in such analyses. \n8:00 AM California or 11:00 AM Boston or 5:00 PM Paris or 8:30 PM Delhi

SUMMARY:Jonas Koppe
DESCRIPTION:Frequency-modulated RF pulses in solid-state NMR: Principles and Applications  \nAdvanced radio-frequency (RF) pulse schemes have found wide application in modern NMR. In particular in solid-state NMR experiments\, where signals can extend over large frequency ranges\, frequency modulation is of special importance\, as it provides a way to overcome the bandwidth limitations of conventional RF pulses and has become a central element of what is today known as wideline or ultra-wideline NMR spectroscopy.\nIn this tutorial\, I will introduce the basic principles of frequency-modulated RF pulses\, discuss their design principles and optimal experimental implementation\, and highlight typical applications in solid-state NMR. \n8:00 AM California or 11:00 AM Boston or 5:00 PM Paris or 8:30 PM Delhi

SUMMARY:Jacob Holmes
DESCRIPTION:NMR Structure Determination in Molecular Solids  \nRich chemical understanding is critically important to understanding function in all chemical systems. Here\, we show how the determination of complete three-dimensional structures can be improved and accelerated for materials at natural isotopic abundance using new experimental methods with >100 kHz MAS\, machine-learned chemical shift predictions\, and rapid assignment methods\, to validate structures within hours. We highlight these advances with structure validation using only 1H-detected methods\, the improvement of ShiftML to DFT accuracy\, and the use of probabilistic methods for chemical shift assignment. The methods are combined to determine complete atomic-level structures of disordered molecular solids. \n8:00 AM California or 11:00 AM Boston or 5:00 PM Paris or 8:30 PM Delhi

SUMMARY:Yao Fu
DESCRIPTION:From Cryogenic to Room Temperature: Advances in DNP-MAS for\nMaterials Characterization \nThis presentation highlights recent advances in Dynamic Nuclear\nPolarization (DNP)-enhanced solid-state NMR spanning temperatures from\ncryogenic (30-100 K) to ambient conditions. At cryogenic temperatures\, cross-\neffect DNP was applied to a range of material systems\, including SiO₂\nnanoparticle-polymer composites\, conductive mesoporous polymers\, and the\nmetal-organic framework (MOF) UiO-66. In UiO-66\, DNP-enhanced NMR\nrevealed previously unrecognized water-induced structural rearrangements\, in\nwhich water molecules reversibly replace coordinating linkers to form\nhydrogen-bond-stabilized dangling groups. To overcome limitations associated\nwith exogenous polarizing agents and low-temperature operation\, room-\ntemperature Overhauser DNP was explored in trityl radical thin films relevant\nto OLED technologies. Efficient polarization transfer and site-resolved\nmeasurements of electron delocalization were achieved under ambient\nconditions. Together\, these studies illustrate the evolution of DNP methodologies\nacross a broad temperature range and highlight their growing potential for\ninvestigating increasingly complex and technologically relevant material\nsystems. \n8:00 AM California or 11:00 AM Boston or 5:00 PM Paris or 8:30 PM Delhi

SUMMARY:Yifan Quan
DESCRIPTION:Pentacene: excited triplet\, molecular spin\, polarizing agent\, or quantum sensor?  \nMolecular spin based quantum sensors offer a range of advantages\, from high spin density to functionalization via chemical tunability. Here\, we demonstrate AC vector sensing using the photoexcited spin triplet of deuterated pentacene molecules\, operating at zero external magnetic field and room temperature. We achieve full three-dimensional microwave field reconstruction by detecting the Rabi frequencies of anisotropic spin-triplet transitions associated with two crystallographic orientations of pentacene in naphthalene crystals. We further introduce a phase alternated protocol that extends the rotating-frame coherence time by an order of magnitude. Additionally\, we demonstrate a sizable increase in the coherence time of a pentacene electron spins by hyperpolarizing the proton spin bath via triplet dynamic nuclear polarization. The polarized nuclear spin bath provides a reduced magnetic noise environment\, leading to enhanced electron spin coherence. These results establish pentacene-based molecular spins as a practical and high-performance platform for microwave sensing and nuclear spin as a practical and controllable route to engineering the platform. \n8:00 AM California or 11:00 AM Boston or 5:00 PM Paris or 8:30 PM Delhi
