A THEORETICAL INVESTIGATION OF DEPTQ NMR SPECTROSCOPY FOR I_nS SPIN SYSTEM (I=1/2, S=1/2)

ABSTRACT

The product operator technique is used for analytical description of multipulse NMR experiments. DEPTQ NMR spectroscopy is the combination of basic DEPT and SEMUT-90 NMR spectroscopy. This study presents the analytical description of DEPTQ NMR spectroscopy for a weakly coupled spin system I _n S (I=1/2, S=1/2, n=1,2,3). The obtained analytical results were found to be in good agreement with the experimental and theoretical ones.
