1) {}^2D_{3/2} has 2S+1=2 <=> S=1/2, D<=>L=2, J=3/2. The site gives g-factor=0.8
2) {}^2D_{5/2} has 2S+1=2 <=> S=1/2, D<=>L=2, J=5/2. The site gives g-factor=1.2
3) I don’t see how the g-factor would change for an atom in a metal compared to a free atom. So I gave in the same number as case (1) and got Landé g-factor=0.8.
