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.
