A New N-Channel Maximum Entropy Method in NMR for Automatic Reconstruction of “Decoupled Spectra” and J-Coupling Determination

A new N-channel (or multichannel) deconvolution method of 1D and 2D NMR spectra is presented based on the Maximum Entropy method. In the general case of spectra exhibiting several lines of various fine structures, the method allows simultaneous deconvolution of all lines. While deconvolution is perf...

description A new N-channel (or multichannel) deconvolution method of 1D and 2D NMR spectra is presented based on the Maximum Entropy method. In the general case of spectra exhibiting several lines of various fine structures, the method allows simultaneous deconvolution of all lines. While deconvolution is performed, determination of the values of the coupling constants is possible. Reconstruction of “decoupled” 1D and 2D spectra is also performed in a fully automated approach. The efficiency of the method is illustrated on experimental 1D and 2D spectra. The method has been developed in the GIFA software, a complete package for processing of NMR data available from the authors.
