COMMENTS: The relative absorption spectrum was measured between 210 and 305 nm using a Xe lamp as analysis light source and a 0.25-m monochromator coupled to a 1024 pixel linear diode array detector

An absolute cross section at 248 nm was obtained using the 0.5-m monochromator/photomultiplier device (as used for the photolysis experiments) and a standard Beer-Lambert analysis of the dependence of optical density at 248 nm on the pressure of CH3C(O)Br

The Beer-Lambert plot yielded σ = 2.43×10-19 cm2 molecule-1, which was used to place the relative spectrum onto an absolute basis
