With that knowledge in hand, Mnova proceeds to process all the individual spectra, one after the other and of course, along the only valid dimension (F2).First, Mnova detects that the dropped folder contains an arrayed experiment.What has happened here are basically 2 things: For example, the figure below illustrates the results obtained when a Bruker arrayed folder is dragged and dropped into Mnova: Kinetics and reaction monitoring by NMRĪny good NMR processing software should be able to automatically recognize when an NMR spectrum is an arrayed experiment and will setup all processing operations accordingly.Well known examples of NMR arrayed experiments are, among others: This grouping greatly facilitates processing as, in general, all subspectra require the same processing operations (apart from some occasional minor adjustments of one or several spectra). All resulting spectra are now treated as a single experiment. Instead of acquiring independent spectra, it is more convenient to create an array with increasing PFG amplitudes. The modus operandi is better explained with an example: let’s suppose it is necessary to acquire a pulse field gradient (PFG) experiment. However, unlike with actual 2D spectra, arrayed spectra are only transformed along the F2 –horizontal or direct- dimension (assuming 1D arrayed spectra only). In the case of Varian, the file name is fid (Varian uses the same name for 1D, 2D, 3D, … and arrayed spectra).

For example, in the case of Bruker spectra they have the same file name as 2D spectra, that is ser files (ser = serial spectra). These experiments are also known as ‘pseudo-2D’. The concept is very simple: an arrayed experiment is basically a set of individual spectra acquired sequentially and related to each other through the variation of one or more parameters and finally grouped together to constitute a composite experiment. In this tutorial we shall cover some basic concepts on the analysis of a very important class of NMR experiments, the so-called Arrayed NMR spectra.
