# Atomic spectroscomy, jj coupling

This is rather a straightforward question I believe, but somehow I'm not sure about the wording of it...

## Homework Statement

Calculate g value (Landé g factor) for sd configuration in jj coupling.

## Homework Equations

$g = 1 + \frac{J(J+1) - L(L+1) + S(S+1)}{2J(J+1)}$

## The Attempt at a Solution

For a d electron there are two j-values: 3/2 and 5/2. And then both can couple with the s electron to give 2/2, 4/2 and 4/2, 6/2 total J. So how can I calculate the g factor, there are many possibilities, correct?
