So far I have found two completely different values of the electron magnetic moment and i need help to know in which cases these are applicable:(adsbygoogle = window.adsbygoogle || []).push({});

They both refer (i think) to values of the particle as such, without orbital contribution. Just the spin contribution to the magnetic moment

1st:

the magnetic moment of the electron is 1.73 Bohr magnetons

http://hyperphysics.phy-astr.gsu.edu/Hbase/spin.html#c6"

2nd:

the magnetic moment of the electron is 1.0011596521931 Bohr magnetons

http://www.isis.rl.ac.uk/neutronSites/index.htm?content_area=/neutronSites/constants.htm&side_nav=/neutronSites/neutronsitesSideNav.htm&" [Broken]

You have to look up : (Electron magnetic moment in Bohr magnetons)

the first one has to do with the fact that according to wave mechanics the magnitude of the spin angular momentum is not a multiple of the quantum number s but sqrt[s(s+1)].

It is the value normally used to predict magnetic moments in transition-metal coordination chemistry.

The second one is the value experimentally measured and appears everywhere.

Are they both correct?

When can we use which?

thanks
