Sentence examples for nmr it from inspiring English sources

For NMR, it allows statistical analysis of compound concentration data obtained by quantitative metabolic profiling or of H NMR spectral signatures (after data reduction with bucketing) for urine samples for example.

The question is: how many different domains must be mapped before biochemists can make accurate predictions about the structure of any new protein, without the need to X-ray or NMR it?In this section Strategic thinking A place like home?

Like in NMR, it is possible to use lumped elements; coils can confine the microwave field to volumes that are much smaller than the wavelength.

However, by NMR, it is difficult to accurately assign the molecular level precursor silicate structures at the pre-nucleation stages of zeolite synthesis.

Since the OMe appeared slightly upfield at δ 3.98 in 1H NMR, it was placed at C-4 and not at C-1, obviously indicating that C-1 is substituted by a hydroxy group.

By comparing HRMAS results with those of ethanol extracts of the same petals analyzed by liquid-state NMR, it was observed that extraction favored hydrolysis reactions, thus decreasing the reliability of NMR results in the liquid-state.

For 1H-NMR it works as follows: the predictor spans the n-sphere of radius n max around the proton of interest, encodes the resulting fragment as a HOSE code, and queries it on the database.

However, without the detailed information about P forms and their dynamics that can be obtained from the use of advanced studies such as P-NMR, it will be more difficult to develop appropriate strategies to improve P use efficiency.

With this method, unlike solid state 29Si-NMR, it is possible to measure the relative concentrations of the organic groups bonded to silica when two silylating reagents are used, and to qualify in an indirect way how the weak silanol groups change during the different post synthesis treatments of a mesoporous silica.

In the study of abietic acid (5), by using MAS-NMR, it was found that the molecule of abietic acid (5) was located in the upper part of the palisade structure of the membrane.

Although Fathiazad et al. [ 27] used DMSO-d6 as the deuterated solvent for running  H-NMR, it has been suggested that methanol-d4 (CD3OD) is more suitable for use with high polarity target samples in small amounts, since the sample could be re-evaporated and re-used.
