6. Comments: The threshold 83723.2 cm -1 a mentioned in slide 4 could be the major reason for The large I(Br+)/I(HBr+) ratio observed for: 1)E(v´=3), 0 = 84249.6 cm -1 see: https://notendur.hi.is/jil3/work/HBr/E%20states%20for%20HBr.pdfhttps://notendur.hi.is/jil3/work/HBr/E%20states%20for%20HBr.pdf 2)H(v´=2), 0 = 84042.1 cm -1 see: https://notendur.hi.is/jil3/work/HBr/H%20states%20for%20HBr.pdfhttps://notendur.hi.is/jil3/work/HBr/H%20states%20for%20HBr.pdf What are the IR for V(m+14) and higher V levels like???? Are these perhaps showing negligible HBr+ signals?! I can not find REMPI spectra for this region. Where do I find processed REMPI spectra for 0 > 83000 cm -1 ? a: that energy corresponds to a threshold, - below which four photons are needed to form Br+ (i.e. (2r + 2i) REMPI) and - above which three photons are needed to form Br+ (i.e. (2r + 1i) REMPI
