INEPT NMR Spectroscopy of ¹⁴ND_n groups: Product operator theory and simulation

Product operator formalism is widely used for the analytical description of multi-dimensional and multiple-pulse NMR experiments for the weakly coupled spin systems having spin-1/2 and spin-1 nuclei. The INEPT NMR experiment is a polarization transfer experiment including J-coupling. In this study, the INEPT NMR experiment was analytically investigated by using product operator theory for weakly coupled IS_n (14ND_n)(I=1, S =1; n=1, 2, 3) spin systems. The obtained theoretical results represent the FID values of 14 ND _n groups. In order to make Fourier transform of the obtained FID values, a Maple program is used and then simulated spectra of the INEPT experiment are obtained for 14 ND_n groups. Then, the experimental suggestions are made for the INEPT NMR experiment of 14 ND_n groups. Also, it is suggested that the INEPT NMR experiment of IS (I=1, S=1) spin system can be used in NMR quantum computing.
