Postprocessing Methodologies for NMR Data

As described in Section 10.2, the final output from the NMR spectrometer to the computer is an FID. Typically 2048 096 digital points are accumulated in the FID and the next step is to improve the potential resolution of the FID by zero-filling the FID to 16384 digital points by adding zeroes to the end of the FID. Upon Fourier transformation (FT) the resultant spectrum contains 16384 points describing a spectral width of 2000-4000 Hz depending on the settings in the ADC. 

The databases of NMR data that are the basis of chemometric model development for on-line process control can be developed via several different processing approaches.
