The GNAT: A new tool for processing NMR data

NMR diffusion (a.k.a. DOSY[26,27]) data, although some-times used for other purposes. The first official version was released in 2009, and it has since become a useful tool for many scientists, complementing other NMR software. Here, we describe the GNAT (General NMR Analysis Toolbox), a free and open‐source platform, released under

Concerning these facts silicon NMR had a slow start. After the first report by Lauterbur et al. in 1962 [2] there have been a few papers per year only. However, since the beginning of the 80´s this has changed dramatically. Our own data collection of 29Si chemical shifts now contains about 13.000 data sets for more than 6.500 com-pounds [3].

For both A and B protons, the peaks are spaced by 0.1 ppm, equal to 6 Hz in this instrument. This time, the peak spacing is 0.1 ppm. This is equal to a J constant of (0.1 ppm 60 MHz) = 6 Hz, the same as before.

rapidly progressed. In the 1980's, biomedical NMR research was dominated by mid- and high-field magnets with Bo values as high as 4.1 T (22). Clinical NMR scanners evolved, too whole-body magnets up to 2.0 T were available (31). Finally, the early 1990's saw the clinical NMR scanner settle at Bo = 1.5 T. This occurred due to 1) high-field
