A Product Operator Theory of 13C Spin-Echo J-Modulation NMR Spectroscopy for CDn (n = 1,2,3) Groups

Abstract

Product operator formalism is widely used for analytical description of multiple-pulse NMR experiments for a weakly coupled spin systems. 13C spin-echo J-modulation NMR spectroscopy for CH<inf>n</inf> ve CD<inf>n</inf> groups is used for identification of different carbon groups. In this study, by using the product operator technique, the analytical description of 13C spin-echo J-modulation NMR spectroscopy for CD<inf>n</inf> (n = 1,2,3) groups is presented and the experimental identifications of 13C NMR signals of CD<inf>3</inf>, CD<inf>2</inf> and CD groups and also quaternary carbons are discussed.
