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 subspectral editing with a multiple quantum trap (SEMUT) NMR spectroscopy is used for subspectral editing of CH3 , CH 2 , CH and C groups. In this study, after obtaining the evolutions of ISF and IS 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 SEMUT NMR for CD" groups. Then, theoretical discussion and experimental suggestions for the subspectral editing of CD" CD 2 , CD and C groups are presented.

A Product Operator Theory of DEPTQ NMR Spectroscopy for ISn(I = 1/2; S = 1; n = 0, 1, 2, 3) Spin Systems

“…The product operator theory as a quantum mechanical method is widely used for analytical description of multipulse NMR experiments on weakly coupled spin systems in liquids having spin-1/2, spin-1 and spin-3/2 nuclei [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. This method not only allows the confirmation of experimental results but also offers to make some experimental suggestions on NMR experiments.…”

“…This method not only allows the confirmation of experimental results but also offers to make some experimental suggestions on NMR experiments. By using product operator theory, SEMUT NMR spectroscopy is applied to CD n groups [16]. Experimental and theoretical investigation of 13 C DEPT NMR spectroscopy for CD n * corresponding author; e-mail: isaka@omu.edu.tr systems is presented elsewhere [13].…”
