Studying the Zeeman Effect on Molecules

Click For Summary
SUMMARY

The Zeeman effect describes the splitting of energy levels in molecules due to an applied magnetic field, with the energy difference quantified by the equation ΔE = μB · B, where μB is the Bohr magneton. In molecules, spin-degenerate energy levels exhibit different responses to magnetic fields, leading to observable splitting. Understanding this phenomenon requires familiarity with the Stern-Gerlach experiment and the Dirac equation, which provide foundational insights into the effect's theoretical underpinnings.

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.
 
Physics news on Phys.org
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:

\Delta E = \mu_B \cdot \overline{B}

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.
