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.
