The isolated trioxide is a colourless solid at \u221240\u2009\u00b0C and is characterised by IR, Raman, UV and NMR spectroscopy. The compound is thermally stable up to \u221230\u2009\u00b0C and decomposes with a half\u2010life of 1 min at room temperature. Between \u221215 and +14\u2009\u00b0C the activation energy for the dissociation is 86.5 kJ\u2009mol<jats:sup>\u22121<\/jats:sup> (20.7 kcal\u2009mol<jats:sup>\u22121<\/jats:sup>).
