It is important to note the discrete nature of transitions vs. the non-discrete (aka continuous) nature of lines, peaks, and patterns. The latter are observable elements of the experimental NMR spectra, and the contemporary borderline of experimental resolution is between peaks and lines. Reflecting the underlying QM theory, transitions are not observed but can be computed and form the basis of calculated (aka theoretical) spectra. One intrinsic value of the QM model in NMR is that it allows the dissection of fully degenerate (not degenerated) lines in observed NMR spectra, i.e., lines that originate from different spin particles but still have the same frequency (isochronic) and, thus, are indistinguishable by classical (visual) analysis. This enables the accurate determination of the essential NMR parameters, even in the presence of severe peak/line overlap and higher-order effects.
