Quantification of electric-field gradient in the supercage of Y zeolites with 131Xe (I = 3/2) NMR
The electric-field gradients in the supercage of HY and steam-dealuminated Y zeolites have been quantified using one-dimensional nutation NMR applied to physisorbed 131Xe. Their values are 1.25 and 0.81·1019 V·m–2, respectively. The composite-pulse sequence used to detect 131Xe signal also cancels the ringing signals from the NMR probe head. The fitting program for extracting the quadrupole coupling constant from the nutation NMR data is available in the web site http://www.pascal-man.com.
