Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:

Charge-neutral[edit]

Anions[edit]

Cations[edit]

Atmospheric sciences[edit]

In atmospheric chemistry:

  • NOx (or NOx) refers to the sum of NO and NO2.[1][2]
  • NOy (or NOy) refers to the sum of NOx and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NOx, HNO3, HNO2, etc.)
  • NOz (or NOz) = NOyNOx

Stability[edit]

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.
