Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:
Charge-neutral
Nitric oxide (NO), nitrogen(II) oxide, or nitrogen monoxide Nitrogen dioxide (), nitrogen(IV) oxide Nitrogen trioxide (), or nitrate radical Nitrous oxide (), nitrogen(0,II) oxide Dinitrogen dioxide (), nitrogen(II) oxide dimer Dinitrogen trioxide (), nitrogen(II,IV) oxide Dinitrogen tetroxide (), nitrogen(IV) oxide dimer Dinitrogen pentoxide (), nitrogen(V) oxide, or nitronium nitrate Nitrosyl azide (), nitrogen(−I,0,I,II) oxide Nitryl azide () Oxatetrazole () Trinitramide ( or ), nitrogen(0,IV) oxide
Anions NameFormulaNitroxide or Nitrite or Nitrate or Peroxynitrite or Peroxynitrate or Orthonitrate or Hyponitrite or Trioxodinitrate or hyponitrate or Nitroxylate or Dinitramide or
Cations Nitrosonium ( or ) Nitronium ( or )
Atmospheric sciences In atmospheric chemistry: (or NOx) refers to the sum of NO and .United States Clean Air Act, (or NOy) refers to the sum of and all oxidized atmospheric odd-nitrogen species (e.g. the sum of , , , etc.) (or NOz) = − Mixed Oxides of Nitrogen ("MON"): solutions of nitric oxide in dinitrogen tetroxide/nitrogen dioxide.
Stability Due to relatively weak N–O bonding, all nitrogen oxides are unstable with respect to and , which is the principle behind the catalytic converter, and prevents the oxygen and nitrogen in the atmosphere from combusting.
