A theoretical application of SEMUT NMR spectroscopy to deuterated compounds

Abstract

The product operator formalism is widely used for analytical description of multiple-pulse nuclear magnetic resonance (NMR) experiments for weakly coupled spin systems. C-13 subspectral editing with a multiple quantum trap (SEMUT) NMR spectroscopy is used for subspectral editing of CH3, CH2, CH and C groups. In this study, after obtaining the evolutions of IxSy2 and IySy2 product operators under the spin-spin coupling Hamiltonian for IS (I = 1/2, S = 1) spin system, the product operator technique was applied for the analytical description of C-13 SEMUT NMR for CDn groups. Then, theoretical discussion and experimental suggestions for the subspectral editing of CD3, CD2, CD and C groups are presented.
