abstract = {The bond strength of chlorine peroxide (ClOOCl) is studied
by photoionization mass spectrometry. 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.},
