Abstract: Abstract Solid-state nuclear magnetic resonance (SSNMR) techniques of 13C multiple cross polarization (multiCP), 13C multiCP with recoupled dipolar dephasing (multiCP/DD) and two-dimensional (2D) 1H–13C heteronuclear correlation (HETCOR) were used to characterize Dachengzi oil shale kerogen.… read more here.

Abstract: Improved multiple cross polarization (multiCP) pulse sequences for quickly acquiring quantitative 13C NMR spectra of organic solids are presented. Loss of 13C magnetization due to imperfect read-out and storage pulses in multiCP has been identified… read more here.
