Show more >The vibrational eigenmodes of dumbbell-shaped polystyrene nanoparticles are recorded by Brillouinlight spectroscopy (BLS), and the full experimental spectra are calculated theoretically. Different fromspheres with a degeneracy of (2l + 1), with l being the angular momentum quantum number, theeigenmodes of dumbbells are either singly or doubly degenerate owing to their axial symmetry. The BLSspectrum reveals a new, low-frequency peak, which is attributed to the out-of-phase vibration of the twolobes of the dumbbell. The quantization of acoustic modes in these molecule-shaped dumbbell particlesevolves from the primary colloidal spheres as the separation between the two lobes increasesShow less >
