Where is the Luttinger liquid in one dimensional semiconductor quantum   wire structures?
  We present the theoretical basis for analyzing resonant Raman scattering experiments in one-dimensional systems described by the Luttinger liquid fixed point. We make experimentally testable predictions for distinguishing Luttinger liquids from Fermi liquid and argue that presently available quantum wire systems are \textit{not} in the regime where Luttinger liquid effects are important.
