MUPen2DTool: a Matlab Tool for 2D Nuclear Magnetic Resonance relaxation data inversion

Abstract: Accurate and efficient analysis of materials properties from Nuclear Magnetic Resonance (NMR) relaxation data requires robust and efficient inversion procedures. Despite the great variety of applications requiring to process two-dimensional NMR data (2DNMR), a few software tools are freely available. The aim of this paper is to present MUPen2DTool, an open-source MATLAB based software tool for 2DNMR data inversion. The user can choose among several types of NMR experiments, and the software provides codes that can be used and extended easily. Furthermore, a MATLAB interface makes it easier to include users own data. The practical use is demonstrated in the reported examples of both synthetic and real NMR data.
