  Resonant inelastic light scattering experiments at $\nu=1/3$ reveal a novel
splitting of the long wavelength modes in the low energy spectrum of
quasiparticle excitations in the charge degree of freedom. We find a single
peak at small wavevectors that splits into two distinct modes at larger
wavevectors. The evidence of well-defined dispersive behavior at small
wavevectors indicates a coherence of the quantum fluid in the micron length
scale. We evaluate interpretations of long wavelength modes of the electron
liquid.
