Paramagnetic species nitrogen oxides

A superconductor becomes diamagnetic below its critical temperature (greater than the liquid nitrogen temperature for the copper oxide-based superconductors). So if a porous membrane is prepared with superconducting material, it should preferentially repel the paramagnetic species below its critical temperature (Figure 25.5a). The separation mechanism can be explained from the mirror... 

There may be many types of chemical species of interest for a given test. The most common types of analyzers associated with combustion equipment are contained in a rack or cabinet as seen in Figure 33.4. The typical analyzers found in one of these cabinets are a paramagnetic oxygen analyzer, infrared absorpfion carbon monoxide analyzer, UBH analyzer, and a chemiluminescent nitrogen oxide analyzer. Commercial sulfur dioxide analyzers based on infrared or ultraviolet absorption are also readily available to fit into one of these racks. The... 

The three nitrogen oxides NO, NO2, and NO3 are paramagnetic, odd-electron species. Both NO and NO2 are important in the synthesis of nitric acid from ammonia ... 

NO3 Nitrogen trioxide o II Transient, odd-electron, paramagnetic species if recent environmental studies had not implicated this unstable compound as a serious pollutant, it would scarcely merit mention among the oxides... 

The Lewis structures of the oxides of nitrogen are shown in Figure 21.6. Two of these species, NO and NO are paramagnetic, with one impaired electron. When nitrogen dioxide is cooled, it dimerizes the unpaired electrons combine to form a single bond between the two nitrogen atoms ...
