Discussion Overview
The discussion revolves around the Grotrian diagram for hydrogen, specifically questioning why the transition from 4p to 3s is marked as not allowed, while other transitions such as 4s to 3p, 4p to 3d, and 4d to 3p are permitted. Participants explore the rules governing these transitions, including changes in angular momentum and magnetic quantum numbers.
Discussion Character
Main Points Raised
- One participant questions the exclusion of the 4p to 3s transition based on the rules of Δl=±1 and Δm=0,±1, suggesting that these rules yield consistent results for other transitions.
- Another participant asserts that the Grotrian diagram is in error, claiming that the 4p to 3s transition is allowed and should be included.
- A different participant references the consistency of their findings with multiple physics books and online resources, indicating that the exclusion is widely accepted.
- Another participant suggests consulting the NIST Atomic Spectra Database for further clarification on the transitions.
Areas of Agreement / Disagreement
Participants express disagreement regarding the status of the 4p to 3s transition, with some asserting it is allowed while others maintain it is not. The discussion remains unresolved with competing views on the correctness of the Grotrian diagram.
Contextual Notes
Participants rely on various sources and rules for quantum transitions, but there is uncertainty regarding the accuracy of the Grotrian diagram and the interpretations of the transition rules.
