  3. 1hv spectrum corrected/shifted Br atomic lines (2+1)REMPI From “short scans” For spectra corrected for power As Icorr = Imeasured / P5 NB: “mW-power correction” Irel Digitized 1hv spectrum from S.

  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)

  7. It is not clear from the spectra comparison below how to correct relative intensities of Br atomic lines recorded by “long scans” Band step size 0.2 cm-1, since there does not seem to be any systematic relationship in relative intensities when compared with the “short scan” spectra Irel Br atomic lines “mW-power corrected” 0.1 cm-1 step size Br atomic lines “mJ-power corrected” 0.2 cm-1 step size 2hv agust,heima,....CF3Br/Sept10/PXP-291110ks/Br 1D-REMPImW-291110ks-011210ak.pxp

  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 [CF3Br+,2E]c ;5p Rydberg state • whereas atomic lines corresponding to excitations to the region to the • [CF3Br+,2E]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 CF3+ formation analaysis: • See: http://www3.hi.is/~agust/rannsoknir/rempi/cf3br/PPT-201110ak.ppt • and below
