Maximum-likelihood spectral deconvolution can be applied to three- and
four-dimensional NMR spectra, improving resolution by effectively sha
rpening lines in air of the dimensions of the data set. Spectral noise
is simultaneously suppressed and cross-talk between (hyper)planes is
minimized. This method is demonstrated for two three-dimensional data
sets; the method can be combined with linear prediction time extension
of multidimensional free-induction decays and other preparatory data
processing. Multidimensional MLM reconstruction offers promise for fut
ure fully automated data processing and analysis of large NMR data arr
ays used far determination of complex molecular structures from NMR. T
he algorithm is readily adapted to parallel computers, which will exte
nd its practicality for the largest data arrays, including four- and f
ive-dimensional data. (C) 1994 Academic Press, Inc.
