How atoms/particles change the ratio? is it possible? - Unsigned

The following discussion is an archived debate of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the debate was PAGE MOVED - if it's good enough for the IUPAC, it's good enough for me.

[edit] Requested move

Gyromagnetic_ratioMagnetogyric_ratio – The name "magnetogyric ratio" is that which is recommended by IUPAC - the official worldwide Chemistry body responsible for nomenclature, etc. See: http://www.iupac.org/goldbook/M03693.pdf Wikipedia should be consistent with current usage.

This is primarily because the value is a ratio of magnetic (i.e. spin) / orbital angular momentum and not orbital / magnetic. Ctrwikipedia 09:55, 8 September 2006 (UTC)

[edit] "Gyromagnetic" vs "Magnetogyric"

I received a note on my talk page from User:Gillen inquiring about the page move I completed above. Gillen's note:

We need to talk about this gyromagnetic ratio thing. I have never personally heard of the magnetogyric ratio until I had the unpleasant experience of looking at the Lande g factor page today. To say the least, this is disturbing. Please give me more justification for the change than simply some international chemistry reference. Physicists refer to this as gyromagnetic ratio, it appears that chemists think it is the magnetogyric ratio. I can list dozens of physics references that call this the gyromagnetic ratio....please explain to me why they are all wrong?

I'm replying here. I don't have any stake in where this page is; I completed the move because it seemed like a reasonable and cited request, and nobody had opposed after more than a week. Now someone has opposed, so I guess we should talk about it. It would be good to cite an authoritative reference citing each name, if two are in use. The article should be titled according to the most common usage, and the naming discrepancy should be discussed in the article.

All that said, I'm neither a chemist nor a physicist. The Google test gives "gyromagnetic" the edge by 301,000 to 42,100 I would tell the person who requested the move about this discussion, but the account doesn't seem to be active. I'll leave a note at Talk:IUPAC for opinions. Is there a corresponding body that standardizes physics terminology? -GTBacchus(talk) 09:56, 12 November 2006 (UTC)


[edit] "physics references."

I couldnt find a body that standardizes physics nomenclature, but I did send you some references. And posted them on your talk page. —The preceding unsigned comment was added by Gillen (talkcontribs) 22:22, November 15, 2006 (UTC).

Copied from my talk page:
There are literally thousands of papers that clearly and unambiguously indicate that Lande g-factor/g factor/ gyromagnetic ratio are all synonyms for the same thing. I am including a reference from an old paper that will clearly indicate this.
Rev. Mod. Phys. 34, 102–109 (1962) [Issue 1 – January 1962 ]
It is also clearly illustrated in Griffiths "Quantum Mechanics", as well as in Claude Cohen-Tannoudji's "Quantum Mechanics". FYI - Tannoudji is a Nobel Laureate and Griffiths is the most used undergraduate text that I know of. User:140.247.248.124
I've copied the reference information here so it can be worked into the article. I would say the first task is to include in the article discussion of the fact that two names are in common use by different sciences, and if it seems appropriate, we can always move the page back at some point, if it turns out that we find one spelling to be much more common than the other, preferably based on something surer than the "google test". -GTBacchus(talk) 19:53, 20 November 2006 (UTC)

[edit] Inconsistency with Larmor frequency page: "also known as Lange G-factor"?

This page indicates that the magnetogyric ratio is also known as the Lange G-factor. However, there are important factors that distinguish the two. On the Larmor frequency page, they are defined as proportional, with some important dimensionful factors. I'm inclined to believe the equation on the Larmor frequency page, as the equation makes sense unitwise. —The preceding unsigned comment was added by 129.64.37.157 (talk • contribs) 19:00, November 20, 2006 (UTC).

Furthermore, I believe it's inaccurate to say the magnietogyric ratio is a "unitless quantity" that gives the ratio between the two moments. When used in the context of the Larmor frequency and energy of nuclear spin excitations, it clearly has dimensions of Teslas/second. —The preceding unsigned comment was added by 129.64.37.157 (talk • contribs) 19:02, November 20, 2006 (UTC).
