SUMMARY
Near-resonant atomic transitions occur when an electromagnetic (EM) field's frequency aligns with the energy difference between atomic levels within the natural width of the transition. This phenomenon is influenced by factors such as Doppler broadening and the damping term in the Drude model for oscillators. The result is a broad peak in resonant absorption frequency rather than a sharp peak, allowing for effective excitation of electrons from lower to higher energy states.
