## Abstract Spherical, rod‐ and tetrapod shaped CdSe nanocrystals are investigated by Raman spectroscopy and the longitudinal‐optical and surface optical phonons are observed. We find that the position of the longitudinal‐optical phonon slightly red‐shifts with decreasing diameter, whereas the posi
