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. 13C subspectral editing with a multiple quantum trap (SEMUT) NMR spectroscopy is used for subspectral editing of CH<inf>3</inf>, CH<inf>2</inf>, CH and C groups. In this study, after obtaining the evolutions of I<inf>x</inf>S<inf>y</inf>2 and I<inf>y</inf>S<inf>y</inf>2 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 13C SEMUT NMR for CD<inf>n</inf> groups. Then, theoretical discussion and experimental suggestions for the subspectral editing of CD<inf>3</inf>, CD<inf>2</inf>, CD and C groups are presented. © Springer-Verlag 2001.
