| Common Name | Abbreviation/Symbol |
|---|---|
| Nitric oxidea | NO |
| Nitroxyl anion | NO− |
| Nitrosoniumb | NO+ |
| Nitrogen dioxide | NO2 |
| Peroxynitrite | ONOO− |
| Superoxidec | O2 − |
| Nitrite | NO2 − |
| Nitrate | NO3 − |
| Nitrite + nitrated | NOx |
| Nitrosothiols | RSNO |
1-a The unpaired electron does not need to be written into the abbreviation for NO as NO ·
1-b Although some compounds act as donors of a species with an NO+-like character (i.e., are nitrosating agents), NO+ does not exist as such in aqueous solution.
1-c NO reacts with the superoxide anion to form peroxynitrite.
1-d In some conditions, S-nitrosothiols may also contribute to the NOx measured by chemiluminescence.
