Abstract: Continuous-flow hyperpolarized 129Xe NMR has been used to study how the 129Xe chemical shifts are influenced by the metal cations with different electronic structures substituted on FAU zeolites in order to reveal the relationship between the 129Xe NMR chemical shift and the local electric field in the confined space.
