The experimental results are obtained from the fragmentation threshold yielding ClO+, which is observed at 11.52 +/- 0.025 eV. The O-O bond strength D(o) is derived from this value in comparison to the first ionization energy of ClO, yielding D(o)298 = 72.39 +/- 2.8 kJ mol(-1). The present work provides a new and independent method to examine the equilibrium constant K(eq) for chlorine peroxide formation via dimerization of ClO in the stratosphere. This yields an approximation for the equilibrium constant in the stratospheric temperature regime between 190 and 230 K of the form K(eq) = 1.92 x 10(-27) cm3 molecules(-1) x exp(8430 K/T). This value of K(eq) is lower than current reference data and agrees well with high altitude aircraft measurements within their scattering range. Considering the error limits of the present experimental results and the resulting equilibrium constant, there is agreement with previous works, but the upper limit of current reference values appears to be too high. This result is discussed along with possible atmospheric implications. 000047475 536__ $$0G:(DE-Juel1)FUEK257$$2G:(DE-HGF)$$aChemie und Dynamik der Geo-Biosphäre$$cU01$$x0 000047475 588__ $$aDataset connected to Web of Science, Pubmed 000047475 650_7 $$2WoSType$$aJ 000047475 7001_ $$0P:(DE-HGF)0$$aKühl, S.$$b1 000047475 7001_ $$0P:(DE-Juel1)129164$$aVogel, B.$$b2$$uFZJ 000047475 7001_ $$0P:(DE-Juel1)129138$$aMüller, R.$$b3$$uFZJ 000047475 7001_ $$0P:(DE-Juel1)129158$$aStroh, F.$$b4$$uFZJ 000047475 7001_ $$0P:(DE-Juel1)VDB14301$$avon Hobe, M.$$b5$$uFZJ 000047475 7001_ $$0P:(DE-HGF)0$$aFlesch, R.$$b6 000047475 7001_ $$0P:(DE-HGF)0$$aRühl, E.$$b7 000047475 773__ $$0PERI:(DE-600)2006031-2$$a10.1021/jp044142h$$gVol. 109, p. 6730 - 6734$$p6730 - 6734$$q109<6730 - 6734$$tThe @journal of physical chemistry <Washington, DC> / A$$v109$$x1089-5639$$y2005 000047475 8567_ $$uhttp://hdl.handle.net/2128/747$$uhttp://dx.doi.org/10.1021/jp044142h 000047475 8564_ $$uhttps://juser.fz-juelich.de/record/47475/files/74898.pdf$$yOpenAccess 000047475 8564_ $$uhttps://juser.fz-juelich.de/record/47475/files/74898.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000047475 8564_ $$uhttps://juser.fz-juelich.de/record/47475/files/74898.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000047475 8564_ $$uhttps://juser.fz-juelich.de/record/47475/files/74898.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000047475 909CO $$ooai:juser.fz-juelich.de:47475$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000047475 9131_ $$0G:(DE-Juel1)FUEK257$$bEnvironment (Umwelt)$$kU01$$lChemie und Dynamik der Geo-Biosphäre$$vChemie und Dynamik der Geo-Biosphäre$$x0 000047475 9141_ $$y2005 000047475 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000047475 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000047475 9201_ $$0I:(DE-Juel1)VDB47$$d31.12.2006$$gICG$$kICG-I$$lStratosphäre$$x0 000047475 970__ $$aVDB:(DE-Juel1)74898 000047475 9801_ $$aFullTexts 000047475 980__ $$aVDB 000047475 980__ $$aJUWEL 000047475 980__ $$aConvertedRecord 000047475 980__ $$ajournal 000047475 980__ $$aI:(DE-Juel1)IEK-7-20101013 000047475 980__ $$aUNRESTRICTED 000047475 980__ $$aFullTexts 000047475 981__ $$aI:(DE-Juel1)ICE-4-20101013 000047475 981__ $$aI:(DE-Juel1)IEK-7-20101013
