Zeeman Effect of the Rovibronic Ground State of I^35Cl at Hyperfine Level

Zeeman effect at the hyperfine level of the rovibronic ground state of I^35Cl are determined on the basis of |I_1JF_1I_2FM_F\rangle via an effective Hamiltonian matrix diagonalization method. Perturbations of the Zeeman sublevels are observed and the perturbation selection rules are summarized as well. Several potential applications of such Zeeman effect are suggested.
