(i) joint sampling of K+1 chemical shifts W0, W1, …, WK
em> encoded in K+1 indirect evolution periods of an ND FT NMR experiment,
(ii) phase-sensitive detection of 2K linear combinations of chemical shifts W0±W1±…..±WK,
(iii) editing of the 2K linear combinations of shifts into 2K (N-K)D ‘basic’ projected sub-spectra, so that each contains one of the linear combinations.
