Cross sectional displacement patterns for three low frequency modes with significant Raman intensity. (a) An axial mode at 10.5 cm-1. This mode we identify as the 8.5 cm-1 mode observed in experiment. (b) A radial mode at 20.4 cm-1, expected to be damped by solution. (c) An axial mode at 30.6 cm-1.
