    Undergrad What do the Roman Numerals mean in Spectroscopic Data?

    Thanks for this. It answers the question, but as always raises the other - what about negatively ionised species (Cl-, etc.) ?

    Undergrad What do the Roman Numerals mean in Spectroscopic Data?

    A basic question. Looking at the NIST spectroscopic data, what exactly is, for example, Ar I vs Ar II vs Ar III? If Ar I is unionised Argon, then is Ar II an Ar- ion or an Ar+ ion? (and whichever way around it works, how do we denote the opposite ionisation? If they are all ionized, is there...
