Question

A spectral line caused by the transition ³D₁ →³P₀ experiences the Zeeman splitting in a weak magnetic field. When observed at right angles to the magnetic field direction, the interval between the neighbouring components of the split line is Δω = 1.32x10¹⁰ s^-1 Find the magnetic field induction B at the point where the source is located.

Answer 1

The P term does not split The ³D₁ term splits into 3 lines corresponding to the shift

with M_Z = ± 1, 0. The interval between neighbouring components is then given by
