It is the conjugate acid of peroxynitrite (ONOO−). It has a p''K''a of ~6.8. It is formed ''in vivo'' from the diffusion-controlled reaction of nitrogen monoxide (•NO) and superoxide (O2•−). It isomerises with k = 1.2 s−1, a process whereby up to 5% of hydroxyl and nitrogen dioxide radicals may be formed. It oxidises and nitrates aromatic compounds in low yield. The mechanism may involve a complex between the aromatic compound and ONOOH, and a transition from the cis- to the trans-configuration of ONOOH.〔W. H. Koppenol, P. L. Bounds, T. Nauser, R. Kissner, H. Rüegger, ''Peroxynitrous acid: controversy and consensus surrounding an enigmatic oxidant'', Dalton Trans., 2012, 41, 13779-13787.〕 Peroxynitrous acid is also important in atmospheric chemistry. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Peroxynitrous acid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
