Measurement of Untruncated Nuclear Spin Interactions via Zero- to Ultra-Low-Field Nuclear Magnetic Resonance
John W. Blanchard, Tobias F. Sjolander, Jonathan P. King +5
Zero- to ultra-low-field nuclear magnetic resonance (ZULF NMR) provides a new regime for the measurement of nuclear spin-spin interactions free from effects of large magnetic field…
Long-lived heteronuclear spin-singlet states
Meike Emondts, Micah. P. Ledbetter, Szymon Pustelny +6
We report observation of long-lived spin-singlet states in a 13C-1H spin pair at zero magnetic field. In 13C-labeled formic acid, we observe spin-singlet lifetimes as long as 37 se…
Observation of scalar nuclear spin-spin coupling in van der Waals molecules
Micah Ledbetter, Giacomo Saielli, Alessandro Bagno +2
Scalar couplings between covalently bound nuclear spins are a ubiquitous feature in nuclear magnetic resonance (NMR) experiments, imparting valuable information to NMR spectra rega…
Parahydrogen enhanced zero-field nuclear magnetic resonance
Thomas Theis, Paul Ganssle, Gwendal Kervern +5
Nuclear magnetic resonance (NMR), conventionally detected in multi-tesla magnetic fields, is a powerful analytical tool for the determination of molecular identity, structure, and…
Detection of nuclear magnetic resonance with an anisotropic magnetoresistive sensor
F. Verpillat, M. P. Ledbetter, D. Budker +6
We report detection of nuclear magnetic resonance (NMR) using an anisotropic magnetoresistive (AMR) sensor. A ``remote-detection'' arrangement was used, in which protons in flowing…
