CCL: Two questions to ZEOLITE WORLD



 Dear zeolitists,
 I would be very appreciate to you if you could give me some information
 concerning FAUJASITES (X- and Y-zeolites). I'm especially interesting in
 (NA, LI, K)-zeolites (preferably ANHYDROUS).
 1) Could you give me some references to experimental studies on crystal
 structure of these zeolites (the most recent and the most "reliable"
 as
 well)?
 2) Could you give me some information concerning the partial charges used
 in MOLECULAR MECHANICAL simulations on these types of zeolites?
 Thank you in advance,
 With best wishes,
 Vladislav
