A method of data processing, which suppresses high peaks in NMR spectra, is presented. The algorithm is universal, does not require any information about the shape of subtracted peaks, and can be applied to various types of spectra. In some cases, algorithmic subtraction of peaks in simple 1D spectra can replace more complex and time-consuming methods of experimental peaks suppression. (c) 2006 Elsevier B.V. All rights reserved.
