- TL;DR Summary
- When working in the interaction picture one is free to choose the unitary transformation that seems helpful. How can I show that the dynamics of the problem are independent of such choice.

When working on the interaction picture you can show that in a certain rotating frame the Hamiltonian of a 2-level system (for example) becomes uncoupled. This implies that in such frame there are no Rabi oscillations or other dynamical phenomena, this seems weird to me and I would like to know how is this understood.
