4. It looks as if the a significant change in relative ion intensities, in terms of increasing I(CH+)/I(CH3+) I(CH2+)/I(CH3+) I(Br+)/I(CH3+) -for “Rydberg state + bgr-signals” with energy does not happen significantly untill from about 75395 cm-1 -> 75887 -> 76672 After which it drops, i.e. The mayjor trend is as:

5. I(CH+)/I(CH3+) I(CH2+)/I(CH3+) I(Br+)/I(CH3+) This needs verification (?) from KM (i.e. “table values for relative Intensities”)
