Abstract
Raman scattering and far-infrared absorption spectra of PbS nanocrysta ls with radii of 2 nm are presented. The experimental results are cons istent with theoretical calculations which account correctly for the m echanical boundary conditions at the nanocrystal-host interface, and i nclude the first observation of the mixed or coupled vibrational modes predicted by the theory.
