    hello all

    how we can study the zeeman effect on molecule what is the bases to do it

    or it is the same for atoms.

    Zeeman effect is the splitting of the energy levels in a system due to an applied (or effective - in the case of SO interaction) magnetic field.

    Normally, all the energy levels are spin-degenerate in a molecule. And the up-spin and down-spin levels respond differently to a magnetic field.

    This splitting is given by:

    [tex] \Delta E = \mu_B \cdot \overline{B}[/tex]

    where mu_b is the Bohr magneton.

    You may want to check Stern-Gerlach experiment and Dirac equation if you want to delve into the exact formulation. I guess that's where it's fundamentally derived.
