Nitrogen oxide
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 (NO2), nitrogen(IV) oxide
- Nitrogen trioxide (NO3), or nitrate radical
- Nitrous oxide (N2O), nitrogen(0,II) oxide
- Dinitrogen dioxide (N2O2), nitrogen(II) oxide dimer
- Dinitrogen trioxide (N2O3), nitrogen(II,IV) oxide
- Dinitrogen tetroxide (N2O4), nitrogen(IV) oxide dimer
- Dinitrogen pentoxide (N2O5), nitrogen(V) oxide, or nitronium nitrate [NO2]+[NO3]−
- Nitrosylazide (N4O), nitrogen(−I,0,I,II) oxide
- Oxatetrazole (N4O)
- Trinitramide (N(NO2)3 or N4O6), nitrogen(0,IV) oxide
Anions
- Nitroxyl (NO−)
- Nitrite (NO−
2) - Nitrate (NO−
3) - Peroxynitrite (ONO−
2) - Peroxynitrate (ONO−
3) - Orthonitrate (NO3−
4) - Hyponitrite (N
2O2−
2) - Trioxodinitrate (N
2O2−
3), or hyponitrate - Nitroxylate (N
2O4−
4) - Dinitramide (N(NO
2)−
2 or N
3O−
4)
Cations
- Nitrosonium (NO+
) - Nitronium (NO+
2)
Atmospheric sciences
- NOx (or NOx) refers to the sum of NO and NO2.[1][2]
- NOy (or NOy) = the sum of all oxidized atmospheric odd-nitrogen species (e.g. NOx + HNO3 + HNO2 + etc.)
- NOz (or NOz) = NOy − NOx
Nitric oxide, NO 
Nitrogen dioxide, NO2 
Nitrous oxide, N2O 
Dinitrogen trioxide, N2O3 
Dinitrogen tetroxide, N2O4 
Dinitrogen pentoxide, N2O5 
Trinitramide, N4O6
Stability
Due to relatively weak N-O bonding, all nitrogen oxides are unstable with respect to N2 and O2, which is the principle behind the catalytic converter and prevents the combustion of the atmosphere.
