13 There is inconsistancy in terms of the intensity of CF3 vs 2hv for the datafiles 20560-20610 and 20560-20610-2 (see slides 8 and 11)

18 There is a consistant drop in the intensity of CF3 vs 2hv for the datafiles 20600-20650 and 20600-20650-2 (see slides 15 and 17)

19 Data 20650-20600 (130910), 1D-REMPI : Updated: 170910 agust, heima,...CF3Br/PXP-170910akd.pxp (IGOR file), Layout: 0, Graph: 4 CF3+ 2hv / cm-1

20 Now it is constant (slide 19)! This is inconsistant with the intensity of CF3 vs 2hv for the datafiles 20600-20650 and 20600-20650-2 (see slides 15 and 17) It might be worth comparing the CF3+ spectra with som impurity signals (C2+).. as a reference to see if analogous behaviour is seen for these. Kári (e-mail, 180910): On that day, 13.09.10, we were having troubles with the peaks shifting back and forth and I fear that the laser power was not being monitored properly. None of the measurements were really adequate. Now, these measurements over the region 20560-20650 might need to be redone in order to solve this inconsistency, but_ I suspect that the shifting of the peaks goes hand in hand with lower laser power._ And since the laser power wasn't being correctly monitored, a correction for the data can not be made. I remember being unsatisfied with the first measurement (20560-20610) due to shifting but continued with the next measurement (20600-20650) to see if the problem would solve itself, it of course did not. The region was then scanned back and forth with no progress until we were told to "ignore" the shift so we measured the regions again (20560-20610_2 & 20600-20650_2). But on the next day 14.09.10 we also measured 20650-20600 and there you have constant CF intensity vs 2hv. The measurement was much more stable after Wang had tuned the instruments a bit.
