Why does Raman shift increase as temperature decreases?

  1. Dec 10, 2011 #1
    This was a quick short answer question from a previous final exam I'm studying from - the prof didn't provide an answer key.

    I can't think of any physical reason why this should happen. I can explain why the stokes/anti-stokes intensities vary with temperature, and why the linewidths vary with temperature, but I can't explain why the stokes/anti-stokes shifts actually increase in magnitude at lower temperatures.

    I can't think of any good reason why the zone center optical phonons would have higher energy at lower temperatures...
