We study the influence of inhomogeneous broadening on results obtained from spectrally resolved transient four-wave mixing. In particular, we study the case where more resonances are coherently excited, leading to polarization interference or quantum beats, depending on the microscopic nature of the resonances. To demonstrate the ideas, we present experimental results from bulk CdSe and from GaAs multiple quantum wells.
