Long-lived heteronuclear spin-singlet states in liquids at a zero magnetic field.
We report an observation of long-lived spin-singlet states in a 13C-1H spin pair in a zero magnetic field. In 13C-labeled formic acid, we observe spin-singlet lifetimes as long as 37 s, about a factor of 3 longer than the T1 lifetime of dipole polarization in the triplet state. In contrast to common high-field experiments, the observed coherence is a singlet-triplet coherence with a lifetime T2...
متن کاملPreparation of nuclear spin singlet states using spin-lock induced crossing.
We introduce a broadly applicable technique to create nuclear spin singlet states in organic molecules and other many-atom systems. We employ a novel pulse sequence to produce a spin-lock induced crossing (SLIC) of the spin singlet and triplet energy levels, which enables triplet-singlet polarization transfer and singlet-state preparation. We demonstrate the utility of the SLIC method by produc...
متن کاملLong-lived nuclear spin states in the solution NMR of four-spin systems.
The existence of long-lived nuclear spin states in four-spin systems is explored by solution-state NMR experiments. Long-lived states are proved to exist in three different natural product molecules, each containing either a AA'BB' or a AA'XX' proton spin system. The measured state lifetimes are between four and eight times the spin-lattice relaxation time constants.
متن کاملLong-lived nuclear spin states far from magnetic equivalence.
Clusters of coupled nuclear spins may form long-lived nuclear spin states, which interact weakly with the environment, compared to ordinary nuclear magnetization. All experimental demonstrations of long-lived states have so far involved spin systems which are close to the condition of magnetic equivalence, in which the network of spin-spin couplings is conserved under all pair exchanges of symm...

a ) 400 MHz 1H-NMR spectrum at 300 K of citric acid; b) typical singlet state pattern obtained for t = 1 ms; c) singlet state pattern obtained for t = 3.5 s. The sequence, originally written for the AX case, was applied to the citric acid, an AA’BB’ four spin system. The CW decoupling was set to 3.5 kHz while the timing optimized to obtain the maximum population of the singlet state at the time...
