Continuous dynamical decoupling provides a powerful method to protect decoherence on atomic transitions due to magnetic field fluctuations or electric quadrupole shifts. Here, we analyze the structure of the effective basis under one and two layers of continuous dynamical decoupling. We use this to characterize quadrupole transitions among dynamically decoupled, dressed states, as relevant for ion clocks. Additionally, we characterize effective selection rules and Rabi frequencies.
Finally, this is applied to a quadrupole transition in Ca+ showing accordance with experimental results.
