Ham. Verhulst et al., A NEW ASSIGNMENT OF THE SIGNALS IN NA-23 DOR NMR TO SODIUM SITES IN DEHYDRATED NAY ZEOLITE, Journal of the Chemical Society, Chemical Communications, (5), 1994, pp. 639-640
Spectral simulations of Na-23 MAS and double rotation (DOR) NMR spectr
a of dehydrated NaY zeolite, CaNaY and Mo(CO)(6) adsorbed in NaY allow
the assignment of four signals to the five different Na+ sites.
