Figure 8

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.
