Spectrally and temporally resolved measurements of stimulated Raman scattering (SRS) from flowing ethanol droplets are presented. The equal frequency spacings of the SRS peaks are an order of magnitude smaller than the spacings for morphology-dependent resonances (MDRs) of a perfect sphere. The observed temporal oscillations of the SRS from two segments of the droplet rim are 180 degree(s) out-of-phase and dependent on the azimuthal mode number, m, of the MDR. The observed frequency splitting and precession of the MDR about the symmetry axis of an oblate droplet is consistent with perturbation predictions of the frequency splitting of a (2n + 1)-degenerate MDR of a perfect sphere.
