  In superconductors on triangle lattices, we show that the electronic Raman
spectra in the non-resonant channel are independent of the light polarization
configuration in the scattering. Therefore the light polarization configuration
is no longer a judicious choice to probe the anisotropic nature of the pairing
wave function (as in the case of square lattices). However, we show that the
detailed energy-shift dependence of the spectrum and the effects of impurities
provide useful information that can help identify the possible pairing symmetry
experimentally. These results are relevant to the newly discovered
Na$_x$CoO$_2\cdot y$H$_2$O superconductors.
