The visible absorption spectrum of OBrO, measured by Fouriertransform spectroscopy — •Oliver C. Fleischmann, Matthias Hartmann, Johannes Orphal, Peter Spietz, and John P. Burrows — Institute of remote sensing, University of Bremen, Kufsteiner Straße, 28359 Bremen, Germany

Absorption spectra of the C(2A2) ← X(2B1) electronic transition of OBrO have been recorded using a BRUKER IFS 120 HR interferometer.

Rotational structure of the vibrational bands has been observed in the region from 16000 to 18000 cm−1. Rotational constants of the C(2A2) electronic state have been determined by applying an evolution strategy for shaping the vibrational band system.

Based on bromine budget considerations, an estimation of the absorption cross section of OBrO in the visible spectral range is given.
