An EPR study on nitrogen monoxide adsorbed on sodium ion-exchanged A-type zeolite
Temperature-dependent EPR spectra of nitrogen monoxide (NO) introduced into sodium ion-exchanged A-type (Na-A) zeolite demonstrated that two types of NO monoradical and one NO-NO radical pair were formed on the zeolites and that the thermally less stable NO monoradical was converted into the thermally stable one upon warming from 30 K to 100 K.
