Question

Calculate the Energy levels of Hamiltonian consisting of isotropic Zeeman and isotropic hyperfine interaction for CH4-radical with four equivalent 1H nuclei (H || z). Consider the case thatgβH_z>> hyperfine (>>nuclear Zeeman). Use only the diagonal terms in the Hamiltonian to obtain the approximate values of energy levels! (No need to make the exact diagonalization). Calculate the resonance magnetic fields for allowed transitions with ΔM_S=1, and Δm_I=0 (H || z !!!). Draw approximate (qualitative) figure for hyperfine ESR spectra (magnetic field swept).
