## Abstract Spherical, rodโ€ and tetrapod shaped CdSe nanocrystals are investigated by Raman spectroscopy and the longitudinalโ€optical and surface optical phonons are observed. We find that the position of the longitudinalโ€optical phonon slightly redโ€shifts with decreasing diameter, whereas the posi
