ABSTRACT: 2D J–INEPT NMR experiment is a combination of heteronuclear 2D J–Resolved and INEPT experiments. In this study, 2D J–INEPT experiment was analytically investigated by using product operator theory for weakly coupled ISn (I = ½, S=1; n = 1, 2, 3) spin systems. The obtained theoretical results represent the FID values of CD, CD2 and CD3groups. In order to make Fourier transform of the obtained FID values, a Maple program is used and then simulated spectra for of 2D J–INEPT experiment are obtained for CD, CD2 and CD3 groups. It is found that 2D J–INEPT is a useful experiment for both polarisation transfer and 2D J–resolved spectral assignment for CDn groups in complex molecules.
