title: Evidence of 29Si NMR paramagnetic shifts in rare-earth zeolite LSX.
abstract: Paramagnetic shifts have been observed for the first time in rare-earth zeolites; the 29Si MAS NMR spectra of rare-earth ion-exchanged low silica X show a large range of isotropic chemical shifts that can be attributed to Fermi contact interactions with the lanthanide electronic moments.
