That part of the emission which is induced by a resonant perturbing electromagnetic field. The transition between states, n and m, is governed by the @[email protected] @[email protected] of stimulated emission, \(B_{nm}\). CIDNP emission and @[email protected] action are examples of processes which require stimulated emission.
