- We studied the two-level spin resonance in a new perspective. Using the Floquet theory, the periodic interaction Hamiltonians were transfromed into a time-independent interaction. Using the Brillouin-Wigner perturbation method, a degenerated subspace is constructed, where the effective Hamiltonian is given in a perturbation expansion. In this framework, we found that the upper triangular element $\langle α| H^1 | β\rangle$, determines whether the resonance happens. The generalized Rabi frequency and the Bloch-Siegert shift were solved straightforwardly as the first order and the second order solution, proving the benefit of the developed method.
