Sentence examples for decoupling strength from inspiring English sources
The decoupling strength was adjusted to around 10 30 kHz nutation frequency, which represented a good compromise between sample heating at high power and additional line broadening (T2 reduction) at low power.
Proton decoupling field strength of γB1/2 π = 70 kHz was used.
A comparison of different 1H-decoupling schemes in CPMAS at νR of 100 kHz for the same sample demonstrated that low-power WALTZ-16 decoupling unexpectedly displayed superior performance over traditional low-power schemes designed for SSNMR such as TPPM and XiX in a range of decoupling field strengths of 5 20 kHz.
Typical π/2 pulse lengths of 3.5 μs (C) and 4.5 μs (H), continuous wave proton decoupling with field strength of 60 kHz, cross-polarization time of 1 ms and recycle delays of 2 s were used.
The proportion of unreacted methacrylate groups determined using n.m.r. was essentially unaffected by spin rate, dipolar decoupling field strength and temperature, but was only about one-half that determined using infra-red spectroscopy.
The 1H decoupling field strength was |γB 1|/2π = 65 kHz during the period of 2 t r = 0.14 ms duration before the Hahn echo, and ca. 55 kHz during signal detection.
The range of chemical shifts to be decoupled determines the strength of the gradient required, so increasing the shift range again reduces the slice thickness and hence the sensitivity.
I will also demonstrate how these observations can be used to evaluate this decoupling scale and estimate the strength of the plane-of-the-sky component of the embedded magnetic field in a completely novel way.
The phosphomonoester (PME) signal, which can be resolved into phosphocholine (PC) and phosphoethanolamine (PE) at higher field strengths or by decoupling, together with the phosphodiester (PDE) peak, composed of glycerol phosphocholine (GPC) and glycerol phosphoethanolamine, are indicative of lipid metabolism.
The proposed stabilizer (dimensions, 8.8 × 8.8 × 0.2 mm3) includes a two-axis decoupling XY stage and has sufficient strength to suspend an image sensor (IS) used for anti-shaking function.
The narrow band operation reduces rf field strength, which improves the CH decoupling.
