Confinement of vibronic excitations in semiconductor nanocrystal (NC) quantum dots (QDs) has become a subject of intensive studies in recent years. In this paper we demonstrate the possibility of constructing the spherical QD acoustic phonon eigenmodes by use of nothing but symmetry analysis and apply this treatment to the specific case of CuCl NCs.
