Ramp cross-polarization is used for coherence transfer in "inverse" forms of these experiments, while an orientation at which cosine-squared equals one third is used to enhance resolution in some forms of this technique.
Ramp cross-polarization is used for coherence transfer in "inverse" forms of these experiments, while an orientation at which cosine-squared equals one third is used to enhance resolution in some forms of this technique. Tetramethylsilane is used to create a standard in this technique because it is chemically inert and because its values do not interfere with those of the compounds being studied. The difference in resonance frequencies of the molecule being studied and the standard over the frequency gives the chemical shift, which is plotted in this technique. For 10 points, name this type of spectroscopy in which a magnetic field is introduced to a sample of atoms.
