On GFT Projection NMR Spectroscopy

Defining features of G-matrix Fourier Transform (GFT) projection NMR spectroscopy (Kim and Szyperski, 2003):

(i) joint sampling of K+1 chemical shifts W₀, W₁, …, W_K encoded in K+1 indirect evolution periods of an ND FT NMR experiment,

(ii) phase-sensitive detection of 2^K linear combinations of chemical shifts W₀±W₁±…..±W_K,

(iii) editing of the 2^K linear combinations of shifts into 2^K (N-K)D ‘basic’ projected sub-spectra, so that each contains one of the linear combinations.
