Abstract
The interaction between radiation and a two-level molecular system in the p resence of permanent dipole moments is analyzed. It is found that the nonze ro difference between permanent dipoles induces a polarization that oscilla tes at frequencies omega, 2 omega, 3 omega, etc., where omega is the freque ncy of the electromagnetic field resonant with the two-level system. An ana lysis of the propagation equation of the harmonics shows that even harmonic s are amplified while odd harmonics are absorbed.
