SUMMARY
The Roman numerals in spectroscopic data indicate the level of ionization of elements, with I representing neutral atoms, II for singly ionized atoms, and so forth. For example, Ar I denotes neutral argon, while Ar II signifies an Ar+ ion, indicating it has lost one electron. The discussion clarifies that there is no standard notation for negatively ionized species, such as Cl-, in this context. Understanding these designations is crucial for interpreting spectral lines accurately.
