![]() This spectrum has been processed without applying any weighting function and the resolution is 0.13 Hz/pt. ![]() For example, the figure below shows two calculated Lorentzian peaks with linewidth of 10 Hz, separated by a coupling of 10 Hz, which would be mistakenly interpreted. Moreover, it is possible to directly measure accurate values of J only when the splitting is much larger than the linewidth. However, in many areas of high-resolution NMR the observed resonance lines are broadened in some undesirable way which may complicate, if not prevent, the accurate analysis of e.g. 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.
