Concept
Nitrogen oxide
Summary
Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:
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
Nitrosonium ( or )
Nitronium ( or )
In atmospheric chemistry:
(or NOx) refers to the sum of NO and .
(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.

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 combustion of the atmosphere.
