In other cases, the lines are designated according to the level of [[ion]]ization by adding a [[Roman numeral]] to the designation of the [[chemical element]]. Neutral atoms are denoted with the [[Roman numeral]] I, singly ionized atoms with II, and so on, so that, for example: |

More detailed designations usually include the line [[wavelength]] and may include a [[multiplet]] number (for atomic lines) or [[Molecular spectra or band spectra|band designation]] (for molecular lines). Many spectral lines of atomic [[hydrogen]] also have designations within their respective [[Hydrogen spectral series|series]], such as the [[Lyman series]] or [[Balmer series]]. Originally all spectral lines were classified into series: the ''[[Principal series (spectroscopy)|principal series]]'', ''[[sharp series]]'', and ''[[diffuse series]]''. These series exist across atoms of all elements, and the patterns for all atoms are well-predicted by the [[Rydberg-Ritz combination principle|Rydberg-Ritz formula]]. These series were later associated with suborbitals. |
