Abstract

Product operator theory is widely used for analytical description of multiple pulse nuclear magnetic resonance experiments for weakly coupled spin systems. Distortionless enhancement by polarization transfer and subspectral editing with a multiple quantum trap NMR experiments are used for spectral assignments of C-13 NMR spectra in CHn groups. First, in this study we proposed and showed theoretically that distortionless enhancement by polarization transfer and subspectral editing with a multiple quantum trap experiments can also be used for subspectral editing of C-13 NMR spectra when C-13 nuclei coupled to spin-3/2 nuclei. The product operator technique is applied for the analytical description of C-13 distortionless enhancement by polarization transfer and subspectral editing with a multiple quantum trap NMR spectroscopy for (CXn)-C-13 (I-X = 3/2; n = 1, 2, 3) groups.
