摘要：

NO+, generated from NO and O-2, is an infrared probe for the differentiation of Bronsted sites in the main channels and side pockets of mordenites, and for the location and accessibility of sodium ions in the structure. Na+ ions in cationic positions in the main channels are replaced by NO+, and sodium nitrate is formed. The band assignment was checked by isotopic experiments. (C) 2001 Elsevier Science B.V.
