SUMMARY
This discussion focuses on Zeeman splitting, specifically predicting the components produced in weak applied fields. For the normal Zeeman triplet, the transition 1D2 to 1P1 or 2P(3/2) to 2S(1/2) is identified as correct, contingent on having an even number of electrons forming a state with S=0. The sodium resonance line, originally a doublet at 589.6nm, splits into four components with a frequency difference of 2/3 Lorentz unit (LU) and six components for the 589.0nm line, with identical frequency differences.
PREREQUISITES
- Understanding of Zeeman effect and its implications in atomic transitions.
- Familiarity with sodium's resonance lines and their spectral characteristics.
- Knowledge of quantum numbers and selection rules, particularly the transition rule Δm = +1, 0, -1.
- Basic grasp of Lorentz units (LU) in the context of spectral line splitting.
NEXT STEPS
- Study the detailed mechanics of the Zeeman effect in various atomic systems.
- Explore the calculation of Lande g-factor for multi-electron atoms.
