Spinning‐sideband‐free and spinning‐sideband‐only NMR spectra in spinning samples

摘要: NMR spectra are needlessly confusing when spinning sidebands and isotropic peaks lie on the same curve. Qualitative analysis is impossible if these cannot be distinguished from quantitative measurement frustrated whenever any sideband overlaps other peak. Resolving a spectrum into several curves, one containing only peaks, another first higher frequency sidebands, still lower, etc., eliminates problems. These extra which can generated by an echo technique, do not require acquisition time. An ordinary refocused after two revolutions has S/N ratio as each curve in separated made with total number of acquisitions.
