Zeeman Splitting Calculator
Enter the Landé g-factor, magnetic quantum number change, and field strength. The Zeeman Splitting Calculator instantly computes the energy splitting ΔE and frequency shift.
About the Zeeman Splitting Calculator
The Zeeman Splitting Calculator is a precise, scientifically accurate tool that computes the energy level splitting in a magnetic field — the famous Zeeman effect discovered by Pieter Zeeman in 1896. This Zeeman Splitting Calculator implements the standard formula ΔE = g μ_B B Δm_j for normal Zeeman effect and anomalous cases using the Landé g-factor. Proudly supported by Agri Care Hub.
Scientific Formula
g = Landé g-factor
μ_B = Bohr magneton = 9.274 × 10⁻²⁴ J/T
B = magnetic field (Tesla)
Δm_j = change in magnetic quantum number (±1 for σ, 0 for π)
Why This Calculator Is Essential
The Zeeman effect is fundamental in: • Atomic spectroscopy and astrophysics (stellar magnetic fields) • NMR and MRI (proton splitting) • EPR/ESR (electron spin resonance) • Quantum computing (spin qubits) • Precision measurement and atomic clocks It was key evidence for quantum mechanics and earned Zeeman the 1902 Nobel Prize.
How to Use
- Select a preset or enter custom g-factor.
- Enter Δm_j (usually ±1 for allowed transitions).
- Enter magnetic field B in Tesla.
- Choose output units.

- EPR studies
- Quantum physics education
- Research in quantum magnetism
Scientific Foundation
The Zeeman effect splits degenerate energy levels in a magnetic field due to magnetic dipole interaction. The normal Zeeman effect (g=1) applies to spin-zero states, while the anomalous Zeeman effect uses the Landé g-factor from total angular momentum J.
