WebbElectron g-factors . There are three magnetic moments associated with an electron: One from its spin angular momentum, one from its orbital angular momentum, and one from its total angular momentum (the quantum-mechanical sum of those two components).Corresponding to these three moments are three different g-factors: . … Webb(1) Δ E = g β B where β is the constant, Bohr magneton. Since the energy absorbed by the electron should be exactly the same with the state energy difference ΔE, ΔE=hv ( h is Planck’s constant), the Equation 1 can be expressed as (2) h ν = g β B People can control the microwave frequency v and the magnetic field B. facts about notre dame cathedral in paris

The formula g j = 1 + j ( j + 1) + s ( s + 1) − l ( l + 1) 2 j ( j + 1) seems useless in this case. I've seen that g j = 0, because since total angular momentum is zero there is no interaction with the magnetic field.
