The diamond lattice can be thought of as two interlocking face centered
cubic (FCC) lattices. There is a single peak in the Raman spectrum of
pure diamond which arises from the motion of the two lattices relative to
one another, such that all the unit cells throughout the lattice are
exactly in phase. Please use the buttons above to investigate.
Click on the peak in the spectrum to start the animation and anywhere
else to restore the static image.
