  We measured the temperature dependence of low-frequency Raman spectra in
Li$_2$RuO$_3$, and observed multipeak quasielastic scattering in the Ru
honeycomb polarizations below and above the magnetostructural transition
temperature. We attribute this scattering to the fluctuations of the energy
density in the spin system. High-frequency electronic light scattering was
observed at 2150 $cm^{-1}$. Its intensity increased significantly below the
transition temperature, confirming substantial modification of electronic
structure due to removal of degeneracy in $t_{2g}$-manifold of Ru$^{4+}$ ions.
