A New qNMR Compliant Savitzky-Golay Apodization Function for Resolution Enhancement

Abstract

In this work, we introduce a novel NMR apodization function designed to enhance spectral resolution while maintaining compatibility with qNMR standards. This function is based on a modified Savitzky-Golay filter, adapted for time-domain application. It effectively suppresses the negative components typically associated with derivative spectra, while also ensuring the preservation of quantitative integrity in NMR analyses.

Keywords: Savitzky–Golay; apodization; derivative; qNMR; resolution enhancement.
