Question

Explain the splitting of spectral lines in normal Zeeman effect for 2s-1s transition..

Answer 1

The spectral lines of mercury vapor lamp at wavelength 546.1 nm, showing anomalous Zeeman effect. (A) Without magnetic field. (B) With magnetic field, spectral lines split as transverse Zeeman effect. (C) With magnetic field, split as longitudinal Zeeman effect. The spectral lines were obtained using a Fabry–Pérot interferometer.

Zeeman splitting of the 5s level of 87Rb, including fine structure and hyperfine structure splitting. Here F = J + I, where I is the nuclear spin (for 87Rb, I = 3⁄2).
