- Abstract
- A critical review of the heat of formation of HNO is presented. This molecule and, therefore, its thermodynamics parameters play crucial roles in the chemical mechanism of propellant combustion and NOx pollutant chemistry. It was found that predissociation experiments, which have gone largely unnoticed for over 15 yr, lead to a significant revision in the recommended value. Heats of formation of NO, NH2OH, HNO+ and HNO- are also briefly examined, and recommendations are made. Finally, recommendations for future experiments and a brief survey of methods of production of HNO are given in the hope that these will facilitate future studies.
