Generation of nitric oxide by photolysis of silver hyponitrite in suspension induced by LMCT excitation

Abstract

The yellow colour of silver hyponitrite is attributed to a LMCT band at lambda(max) = 419 nm. Solid A(2)N(2)O(2) and its suspensions in water or acetonitrile are light sensitive. LMCT excitation leads to a photolysis according to the equation Ag2N2O2 -> 2Ag + 2NO. In the presence of air and water, NO is finally converted to HNO2. (c) 2007 Elsevier B.V. All rights reserved.
