Infrared overtone spectroscopy and unimolecular decay dynamics of peroxynitrous acid
The Journal of Chemical Physics, 2005Peroxynitrous acid (HOONO) is generated in a pulsed supersonic expansion through recombination of photolytically generated OH and NO2 radicals. A rotationally resolved infrared action spectrum of HOONO is obtained in the OH overtone region at 6971.351(4)cm−1 (origin), providing definitive spectroscopic identification of the trans-perp (tp) conformer of

Hydroxyl Radical Formation during Peroxynitrous Acid Decomposition
Journal of the American Chemical Society, 1999Yields of O2 formed during decomposition of peroxynitrous acid (ONOOH) under widely varying medium conditions are compared to predictions based upon the assumption that the reaction involves formation of discrete •OH and •NO2 radicals as oxidizing intermediates.

Kinetics of Peroxynitric Acid Reactions with Halides at Low pH
The Journal of Physical Chemistry A, 2000The oxidation of iodide, bromide, and chloride by peroxynitric acid (HOONO2) was studied by spectroiodometry. The second-order rate constants were found to be 890 (I-, 295 K), 0.54 (Br-, 295 K), and 0.0014 M-1 s-1 (Cl-, 298.2 K). No pH dependence was observed in any of the systems (pH 1.2−4.9).

Kinetics and mechanism of the formation and decay of peroxynitrous acid in perchloric acid solutions
Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1970The kinetics of the formation of peroxynitrous acid (HOONO), and its decay to nitrate ion have been studied in perchloric acid solutions (0·01 to 1·0 mol I–1) by the stopped-flow method. The rate law for the formation process was found to be of the form (a, b, and c are constants)d[HOONO]//dt=a[H+][H2O2][HNO2]//b+c[H2O2], which is consistent with a ...
