Nitroxyl (common name) or azanone (IUPAC name)[2] is the chemical compound HNO. It is well known in the gas phase.[3][4] Nitroxyl can be formed as a short-lived intermediate in the solution phase. The conjugate base, NO, nitroxide anion, is the reduced form of nitric oxide (NO) and is isoelectronic with dioxygen. The bond dissociation energy of H−NO is 49.5 kcal/mol (207 kJ/mol), which is unusually weak for a bond to the hydrogen atom.
