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

Abstract

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 ISn (14NDn)(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 NDn groups. Then, the experimental suggestions are made for the INEPT NMR experiment of 14 NDn 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. © tÜbÏtak.
