Reconstruction of phase-sensitive two-dimensional NMR spectra by maximum entropy

摘要: The problems of reconstructing phase-sensitive 2D NMR spectra using conventional methods and the advantages our previously proposed implementation maximum entropy method (MEM) are analyzed. It is shown that when a spectrum reconstructed MEM, higher resolution can be obtained for given measuring time. should prove to most useful, however, applied reconstruction cannot after data processing phased such all peaks have pure absorption phase. MEM capable producing spectra. For example, COSY cross diagonal separated into subspectra where In effect this also removes from spectrum. Finally reducing t1 noise.
