How this entity was disambiguated
This entity first appeared as the object of triple T3725816 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Lyman series in hydrogen spectrum Context triple: [Theodore Lyman (scientist), knownFor, Lyman series in hydrogen spectrum]
-
A.
Rydberg constant
The Rydberg constant is a fundamental physical constant that characterizes the limiting value of the highest wavenumber (or lowest wavelength) of any photon that can be emitted from the hydrogen atom, playing a key role in atomic spectroscopy and quantum theory.
-
B.
Sommerfeld fine-structure formula
The Sommerfeld fine-structure formula is a relativistic extension of the Bohr model that accurately predicts the fine-structure energy levels of the hydrogen atom.
-
C.
Atombau und Spektrallinien
*Atombau und Spektrallinien* is Arnold Sommerfeld’s influential textbook on atomic structure and spectral lines that helped shape the development of early quantum theory.
-
D.
Stark effect
The Stark effect is the splitting and shifting of atomic or molecular spectral lines caused by an external electric field.
-
E.
Zeeman effect
The Zeeman effect is the splitting of atomic or molecular spectral lines into multiple components when subjected to an external magnetic field, revealing information about energy levels and magnetic moments.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Lyman series in hydrogen spectrum Description of subject: The Lyman series in the hydrogen spectrum is a set of ultraviolet emission or absorption lines produced when electrons in hydrogen atoms transition from higher energy levels down to the ground state (n=1).
