Quantum Transitions in Terms of non-Adiabatic Dressed States
  Nonadiabatic dressed states of a quantum system interacting with an external electromagnetic field and the environment are presented. The relevant matrix elements within the specified states are found. A closed form expression of the quantum transitions based on the nonadiabatic dressed states is proposed for the first time.
