Dr. Thomas Theis is Associate Professor of Chemistry and Physics, and Goodnight Distinguished Scholar in Molecular Characterization at North Carolina State University. His research is focused on hyperpolarization technology and unconventional NMR and MRI detection schemes. Dr. Theis was born in Heidelberg, Germany, raised in Tenerife, Spain, and completed his undergraduate and masters at the Georg-August University of Goettingen (Germany). Theis received his PhD in 2012 from UC Berkeley (USA) working with Prof. Alexander Pines on "zero-field NMR" and “parahydrogen hyperpolarization schemes” for portable NMR. Dr. Theis conducted postdoctoral research at Duke University (USA) with Prof. Warren Warren focused on "singlet states for hyperpolarization storage", and worked on "low-field NMR" as visiting fellow at RWTH Aachen University with Prof. Stephan Appelt (Germany). In 2015, he was promoted to Research Assistant Professor at Duke University developing “cost-efficient hyperpolarization techniques for molecular imaging”. Since 2018, Dr. Theis leads the NC State Hyperpolarization Laboratory at NC State University where he was promoted to Associate Professor in 2023 and received the Goodnitght Distinguished Scholarship. He has received numerous awards in recognition of his research including the Friedrich-Wilhelm-Bessel Award from the Humboldt Foundation and the Ampere Prize for Rising Stars in Magnetic Resonance.

Composite and shaped pulses for efficient and robust pumping of disconnected eigenstates in magnetic resonance
The Journal of Chemical Physics, 140(1), 014201.
TL;DR:
Traditional composite and adiabatic pulses fail completely in this problem because the interactions driving the transitions are fundamentally different, but the new shapes introduced can move population between accessible and disconnected eigenstates over a wide range of radio-frequency amplitudes and offsets while depositing insignificant amounts of power.

Contributors: T. Yacovitch *, E. Garand *, J. Kim *, C. Hock*, * & D. Neumark *
TL;DR:
SEVI spectra of the 2P3/2 bands of FCH4- and FCD4- show extended structure from transitions to the entrance valley van der Waals region and the reactant side of the F + CH4 transition state region, attributed to bending or hindered rotation of the methane moiety and may be a spectroscopic signature of reactive resonances.
