4. NB: We assume that the relative intensities of the Br atomic lines for the “short scans” and low step size (0.1 cm-1) are more reliable than those or the “long scans” and larger step size (0.2 cm-1)

8. The conclusion is that Br atomic lines in the high wavenumber range (> 80000cm-1) need to be rescanned by short scans and small step sizes (0.1 cm-1) in order to obtain more relyable picture of the relative intensities of The bands in that region. Based on the data presented in slide 2, abowe, for Br atomic lines recorded in the range 71000 – 80000 cm-1 (“short scans”, small step sizes) the largest signals are observed for the region of excitation to the [CF 3 Br +, 2 E] c ;5p Rydberg state whereas atomic lines corresponding to excitations to the region to the [CF 3 Br +, 2 E] c ; 5s Rydberg state are very weak. This suggests that the major channel For formation of Br is via excitation to the [CF3Br+,2E]c ;5p Rydberg state. This fits nicely with the results of the CF 3 + formation analaysis: See: http://www3.hi.is/~agust/rannsoknir/rempi/cf3br/PPT-201110ak.ppthttp://www3.hi.is/~agust/rannsoknir/rempi/cf3br/PPT-201110ak.ppt and below
