Experimentally, Raman continuum for A(g) and B(g) geometry exhibits peaks far apart from each other (about 80-150 cm(-1)) in frequency. The former is insensitive to doping over a small range where T(c) does not vary much whereas the latter shifts towards higher frequencies. We calculate the electronic Raman scattering intensities using the 'modified spin bag model'. We show that the calculated results have natural explanation to the observed anomalous peak separation and peculiar doping dependence.
