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 $\mathit{\text{not}}$ in the regime where Luttinger liquid effects are important.
