A simple method for processing NMR spectra in which acquisition is delayed: Applications to in vivo localized 31P NMR spectra acquired using the DRESS technique

It is a requirement of many localized NMR spectroscopy experiments, such as DRESS, that collection of the free induction decay be delayed a significant time after the middle of the last pulse. This leads to distortion of the spectra and seriously impedes the retrieval of quantitative information from these spectra. A technique is described in which a correction function is derived from the convoluted spectrum and is used to produce a spectrum with much reduced distortion from which quantitative information may easily be obtained by conventional techniques. © 1988 Academic Press, Inc.
