author keywords: Hyperpolarization; Singlet state; Long lived state
MeSH headings : Algorithms; Alkynes; Carbon Isotopes; Electromagnetic Fields; Half-Life; Isotope Labeling; Nuclear Magnetic Resonance, Biomolecular / instrumentation; Nuclear Magnetic Resonance, Biomolecular / methods; Reproducibility of Results; Solvents
TL;DR:
It is shown that it is possible to determine (13)C singlet state lifetimes by detecting the naturally abundant doubly-labeled species, which allows for rapid and low cost screening of potential molecular biomarkers bearing long-lived states.

Composite and shaped pulses for efficient and robust pumping of disconnected eigenstates in magnetic resonance
The Journal of Chemical Physics, 140(1), 014201.
Contributors: T. Theis* , Y. Feng*, T. Wu* & W. Warren*
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.

2014 journal article
Accessing Long-Lived Disconnected Spin-1/2 Eigenstates through Spins > 1/2
Accessing Long-Lived Disconnected Spin-1/2 Eigenstates through Spins > 1/2. Journal of the American Chemical Society, 136(43), 15118–15121.
Contributors: K. Claytor *, T. Theis* , Y. Feng*, J. Yu*, D. Gooden * & W. Warren *
MeSH headings : Acetylene / chemistry; Deuterium / chemistry; Magnetic Phenomena; Magnetic Resonance Spectroscopy
TL;DR:
Here the classes of molecules known to have accessible long-lived states are extended to include those with chemically equivalent spin-1/2 nuclei accessed by coupling to nuclei with spin > 1/2, in this case deuterium, and experiments show that simple deuteration of molecules with (13)C pairs at their natural abundance is sufficient for successful lifetime measurements.

Contributors: M. Emondts *, M. Ledbetter*, S. Pustelny *, T. Theis* , B. Patton *, J. Blanchard *, M. Butler *, D. Budker *, A. Pines *
TL;DR:
It is demonstrated that heteronuclear singlet states formed between a 1H and a 13C nucleus can exhibit longer lifetimes than the respective triplet states even in the presence of additional spins that couple to the spin pair of interest.

TL;DR:
It is shown that the wild-type halogenase SyrB2 can indeed direct aliphatic nitration and azidation reactions by the same chemical logic and suggests unrecognized or untapped versatility in ferryl-mediated enzymatic C–H-bond activation.

Mechanistic Consequences of Chiral Radical Clock Probes: Analysis of the Mononuclear Non-Heme Iron Enzyme HppE with 2-Hydroxy-3-methylenecyclopropyl Radical Clock Substrates

MeSH headings : Fosfomycin / biosynthesis; Organophosphonates / chemistry; Oxidoreductases / chemistry; Stereoisomerism
TL;DR:
The results strongly suggest that an internal electron transfer to the iron center subsequent to C–H homolysis competes with ring-opening in the processing of the C2 radical intermediate of HppE-catalyzed reaction.
