Nitrogen dioxide (NO 2 ) is a representative of a family of chemically very active radicals NO x =NO+NO 2 . These radicals catalytically destroy the ozone and play a significant role in other ozone-destroying catalytic cycles. In the polar night NO 2 can deactivate ClO by a termolecular reaction to form the reservoir gas Cl0NO 2 . In this way NO 2 restricts...
A comparison of more important physical, chemical and biological properties of the nitric oxide (NO) and free stable nitroxyl radicals (nitroxides) on the base of their structural similarity is made in the article. The active moiety in the nitroxide molecule represents a sterically hindered nitric oxide. The mechanisms of biological action of the nitroxides and especially of their derivatives with...
