"A combined matrix isolation and ab initio study of bromine oxides";
Journal of Physical Chemistry A, 110 (2006), 20; S. 6472 - 6481.

Bromine oxides have been generated by passing a mixture of Br₂/O₂/Ar through a microwave discharge. The
products were stabilized at 6.5 K in an excess amount of argon. Infrared spectroscopy was used to analyze
the species formed; experiments with enriched ¹⁸O₂ and ab initio calculations were carried out to assist in the
assignment of the spectra. Besides the known species BrO, OBrO, and BrBrO, spectroscopic evidence for
BrOBrO, BrBrO₂, and a new isomer of Br₂O₃ is reported for the first time. Extensive comparisons are drawn
between the present studies and previous experimental and theoretical works. The chemistry involved in the
production of the observed compounds is discussed. The assignments are corroborated by the good correlation
between observed and calculated band positions and intensities.
