List of hyperfine structure of the elements?

Click For Summary

Discussion Overview

The discussion centers around the hyperfine structure frequencies of various elements and their isotopes, with a specific focus on finding comprehensive lists and understanding potential patterns in these frequencies. Participants explore the availability of resources and literature on this topic.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the frequencies of hyperfine structures for elements beyond caesium and hydrogen, seeking online resources for a comprehensive list.
  • Another participant references a 2016 paper detailing numerous newly discovered lines of lanthanum, questioning the reasons behind the large number of entries.
  • A participant expresses interest in identifying patterns in hyperfine structure frequencies and considers the possibility of predicting frequencies for isotopes based on existing data.
  • One participant notes the language barrier of the referenced paper, expressing skepticism about the feasibility of identifying patterns manually.
  • A later reply suggests that the patterns in hyperfine structure may be as complex as those found in other energy levels, implying variability and uncertainty in the data.

Areas of Agreement / Disagreement

Participants express curiosity about the topic and share findings, but there is no consensus on the ability to identify patterns or the implications of the data presented in the literature.

Contextual Notes

Limitations include the language of the referenced paper, potential challenges in manually identifying patterns, and the complexity of hyperfine structure data.

If caesium 133 frequency for its hyperfine structure is 9 192 631 770, and hydrogen is 1 420 405 751.7667 what are the frequencies for the other elements and their isotopes? Is there a list on line some were because this would be a long list. Any help on where to look on line would be appreciated. Thanks.

I have found a paper with a list of "Newly Discovered Lines of Lanthanum Between ##5600 \,Å ## and ##6100\,Å ##" published in 2016. Their list alone contains several hundred entries. This raises the question: Why?

I want to see if there is any patterns in the frequencies. Maybe you could predict the frequency of an isotope or maybe other information. I know other people must of looked at this but I am still curious. How can I find this paper? Thanks.
 
The paper wasn't in English. I don't think there is a chance to identify patterns, at least not manually, but I don't know. I just found it (quickly) as I searched for "hyperfine structure + list" and was surprised to find so many for just one element and even labelled "new".
 
The patterns for hyperfine structure as as "patterned" as those for any other energy level.
