Infrared studies of autoionization of thin films of dinitrogen tetroxide

Abstract

The autoionization of dinitrogen tetroxide to form nitrosonium nitrate in thin films at 150–200 K has been studied using infrared absorption spectroscopy. It is found that at these temperatures and low pressure the process is intramolecular, involving only one of two isomers of the nitrite form (ONONO2). (AIP)
