Proton detection solid-state NMR of exotic & unreceptive nuclei
In session 27 held on 11th May 2021, Dr. Amrit Venkatesh gave a talk on "Proton detection solid-state nuclear magnetic resonance (NMR) of exotic & unreceptive nuclei", via Zoom. The video was recorded live during the presentation and serves as an educative lecture.
Bio: Dr. Amrit Venkatesh received his MSc in Chemistry from the Sri Sathya Sai Institute of Higher Learning, India in 2013. Amrit worked as a research fellow at the M.S. University of Baroda for two years where he gained experience in coordination chemistry and provided solution NMR support. Following a brief internship at the NMR center at IISc Bangalore with Dr. Raghothama, Amrit moved to Iowa State University, USA where he completed his PhD under the guidance of Dr. Aaron Rossini in 2020. Amrit is currently a Marie-Curie postdoctoral fellow in Prof. Lyndon Emsley’s group at EPFL, Switzerland.

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.
