Mw0 (36.74 amu)

Mw1 (36.89 amu)

Mw2 (37.04 amu) / REMPI spectrum:

Mw3 (37.19 amu)

Mw0-3, i.e. average mass spectrum for Mw0 – Mw3:

Mw1-3

Mw=36.74 Mw=36.89 Mw=37.04 Mw=37.19 Average Mw (Mw03) i.e.: (I(36.74)+I(36.89)+I(37.04)+I(37.19))/4

=> It is clearly an improvement to integrate, i.e. sum up mass spectra, (about 4 neighbour mass spectra in this case) Comparison of “averaged 37Cl+” and single 1H+ REMPI spectra:

Average REMPI For Mw -> 37Cl+ REMPI For Mw -> / 37H+ J´=5

=> It looks as if the relatively large intensity of the J´=5 peak is reproducable and consistent, thus for example, it appears for H+ as well as Cl+ Why is this?

Mw , i.e. pnt = i.e. Masses: amu, i.e. Cl+ and HCl+ both isotopomers

All masses added together: i.e.pnts = , corresponding to Mw = amu ! Clearley USELESS!
