| Some newer Bruker NMR systems collect data in a way that must be handled distinctly. In such systems, the initial part of the FID is a zero signal, which then rises to a maximum at a time>0, as shown below. If these data are transformed as is, significant baseline distortions will result at either end of the spectrum, as can be seen below (click here for a larger version): | |||

| These initial data points must be removed from the FID. They are then added to the end of the FID, where they will be largely suppressed by apodization. This procedure can lead to some slight distortions at either end of the resulting spectrum, but they should not interfere with any peaks of interest unless you had not set your spectral window wide enough to start with. | |||
| To perform this correction in NUTS, type rd. The software will read the appropriate parameters from the data file, so accept whatever values are proposed. After the operation, you will see that the data has been shifted to the left, as happens below when you place your mouse over the image (click here for a larger version): | |||
