Decoupling inventory is the process of separating inventory for contingency planning. It is part of the inventory that is set aside and used to protect a manufacturing line against any disruptions. A production line can use several parts in assembling the finished product. A delay or shortage of a component can halt the production process.

And the solid-state NMR Hamiltonians explain why efficient heteronuclear spin decoupling in solids is more demanding and difficult to achieve than in liquid-state NMR. For several decades until about 1995, high-power cw decoupling remained the most common way to achieve heteronuclear spin decoupling in solid-state NMR under MAS (17),(18),(19).

(PDF) T1 Spin decoupling effects on the lineshapes of NMR.

Spin decoupling, which is a type of multiple irradiation, is an artificial way of reversing this condition so that the coupling between nuclei is removed. This is achieved by strongly irradiating a nucleus at its resonance frequency while observing another to which it is coupled. At 200–300°C their spin decoupling begins and formation of O− occurs: At temperatures over ∼ 700°C the peroxy ion disproportionates into molecular oxygen and an anion O 2− , or On heating MgO containing some dissolved water — the release of hydrogen is followed by the release of oxygen.

Continuous-wave RF irradiation leads only in a zeroth-order approximation to a full decoupling of heteronuclear spin systems in solids under magic-angle spinning (MAS). In a higher-order approximation, a cross-term between the dipolar-coupling tensor and the chemical-shielding tensor is reintroduced, providing a scaled coupling term between the. Figure 2.

In the context of the SPIN model checker , AI Planning heuristic search methods have been adapted to SPIN [9, 10], and compilations from Promela to AI Planning languages have been designed. Here we adapt a new method from AI Planning, star-topology decoupling [14, 15], to model checking. Contrary to other methods developed in AI, which.

The U.S. Department of Energy’s Office of Scientific and Technical Information. This process can be described by a spin-diffusion type superoperator, allowing the efficient simulation ofstrongly coupled spin systems under heteronuclear spin decoupling. Low-power continuous-wave decoupling at fast MAS frequencies offers an al- ternative to high-power irradiation by reversing the order of the averaging processes.

Whereas spin decoupling, COSY and TOCSY techniques are used to establish connectivities between protons through bonds, techniques that make use of the nuclear Overhauser effect (NOE), such as 1-D NOE and NOESY, 1- and 2-D GOESY, 1- and 2-D ROESY, can establish connectivities through space.

Heteronuclear Spin Decoupling in Matthias Ernst Magic-Angle-Spinning Solid-State NMR ETH Zürich Matthias Ernst ETH Zürich 2 Heteronuclear Decoupling in Liquid-State NMR Heteronuclear J-coupled two-spin system RF irradiation of the I spins leads to a collapse of the J-split multiplet on the S spins. The performance of heteronuclear spin decoupling sequences in solid-state NMR severely degrades when the proton radiofrequency (RF) nutation frequencies (ν1) are close to or at multiples of magic-angle spinning (MAS) frequency (νr) that are referred to as rotary-resonance recoupling conditions (ν1=n·νr). Recently, two schemes, namely. The problem of spin-decoupling spin I = 1 nuclear with large quadrupolar splittings co& (e.g. deuterium) from dilute 5 spins via double-quantum transitions is dealt with. The normal two-spin-1/2 single-quantum decoupling problem (I = 1/2, S = 1/2) is first dealt with as a reminder of the coherent averaging approach.
