High spectral resolution is important for the measurement of NMR parameters, especially for signal intensities, chemical shifts, and coupling constants. shimming, digital filtering, etc) is usually devoted to ensure optimum resolution. Indeed, resolution is a key concept in high resolution NMR and considerable effort (e.g. However, the most relevant point that will be mentioned here will be the introduction of a novel resolution enhancement technique, the so-called Resolution Booster which, I believe, will represent an important breakthrough in NMR. In this first entry I will introduce some very basic concepts about resolution, why it is important and how it can be improved by means of data processing techniques. As my very first blog entry, I thought it would be appropriate to cover one of the most important and exciting topics in NMR signal processing and analysis, resolution.
