  2. Efni fyrirlesturs • Búið er að fara ítarlega í fræðina á bakvið REMPI og TOF massagreina. • Áhersla er lögð á úrvinnslu mæligagna og hermun með SimIon. • Tækjunum ættu allir að vera kunnugir.

  3. Mælingar • Efni: H-Cl • Skannað yfir 20.972-21.062 cm-1 m.v. orku einnar ljóseindar (Heildarorkubil 83.888-84.248 cm-1). • Notað er (2+1) REMPI sem miðast við að tvær ljóseindir örva efnið og sú þriðja jónar það. • Mældir voru 10.000 punktar (sem samsvara 10 μs) fyrir hvern 0,1 cm-1. Gögnin eru því 896x10.000 fylki.
