Abstract
The photolysis of hydrogen iodide in the presence of nitric oxide has been studied at 25°C (and briefly at 45°C) using the Hg emission at 3130 and 3660 Å. Under these conditions nitric oxide was found to act as a simple inhibitor, reducing equally the quantum yields of hydrogen and iodine. A mechanism is proposed involving HNO as an intermediate. The pressure dependence of the reaction H+NO+M→HNO+M is discussed and the results are compared with those of other workers.Keywords
