Developing coherent definitions or terms used to describe NMR spectra goes well beyond a rather formal clarification and nomenclatural exercise. As shown below, based on theoretical and experimental data, a wider adoption of fully determinant and more precise terminology has the ability to significantly advance NMR as a qualitative and quantitative (qNMR) analytical tool. For example, in the context of qNMR, the ability to clearly differentiate signals from peaks, and peaks from lines, is essential for analytical accuracy and further enables an entirely new level of opportunities for deriving quantitative values (quantitative measures ) from HNMR spectra. The more precise terminology can also benefit the field of NMR metabolomics, where results depend critically on how the users process and/or interpret peaks, signals, lines, multiplets, etc. Definitions of these terms are critical as this determines the size of the integration intervals/regions when bucketing and binning steps are performed prior to integration .
