Sensitivity enhancement of 29Si double-quantum dipolar recoupling spectroscopy by Carr-Purcell-Meiboom-Gill acquisition method

The signal enhancement obtained with Carr-Purcell-Meiboom-Gill train of π pulses in the 29Si double-quantum dipolar recoupled experiment has enabled easy identification of and connectivity between different 29Si sites within the ZSM-5 framework.
