Raman spectra from samples of Pb12, made by allowing colloidal microcrystallites of the layered material to aggregate into a solid, display sharp, low-frequency bands with anomalously high intensity. Virtually absent are the intralayer breathing and shearing modes, prominent in bulk Pb12. These feat
