Atmospheric sciences

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

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 oxygen and nitrogen in the atmosphere from combusting.
