The abundance of multiplets as a blanket term in publications, with the meaning of "unknown splitting pattern", reflects the likewise haphazard handling of other NMR terms that are used and accepted widely, yet may not possess a strictly agreed-upon meaning. As a result, the following terms are frequently used loosely and/or interchangeably: resonance, signal, pattern, peak, line, and transition. Additional terms are associated with them and also used commonly, sometimes as modifiers or to impart favorable or unfavorable differences: splitting, multiplicity/multiplet, resolution, and dispersion. Following their definitions below, the present work uses all these terms in bolded font to highlight their essential nature in NMR nomenclature.
