PENDANT 13C NMR spectroscopy applied to CHn groups

Abstract

Polarization enhancement nurtured during attached nucleus testing (PENDANT) NMR spectroscopy gives signals of quaternary carbon atoms in addition to signals indicative of CH, CH2 and CH3 groups. In this study, using product operator theory, analytical description of PENDANT NMR spectroscopy for CHn (ISn, I = 1/2, S = 1/2, n = 0, 1, 2, 3) spin systems are presented. Simulation and experimental results of PENDANT NMR spectroscopy are also presented. Theoretical results are found to be in exact agreement with the simulation results and in good agreement with the experimental ones. © Tübi?tak.
