Improved baseline recognition and modeling of FT NMR spectra

A new approach to baseline correction is presented. A smoothed spectrum is used for both baseline area recognition and modeling. To complete the model an interpolation technique is employed over the signals area; then the model is subtracted from the spectrum giving a flat baseline. The method has been shown to give excellent results even for spectra with large baseline distortions due to different origins. Copyright 2000 Academic Press.
