Two-magnon Raman scattering intensity is obtained for a two-dimensional (2D) spin-1/2 antiferromagnet in presence of hopping (off-diagonal) and on-site (diagonal) disorder. For hopping disorder it is seen that a minute amount of disorder leads to a substantial broadening of the Raman lineshape. Wher
The Raman scattering of two vibrational overtones of benzene is found to undergo strong preresonance enhancement as the excitation frequency approaches the state, the lowest lying, forbidden electronic transition at 265 am. These preresonance active modes are the first overtone of the 606 cm-l eZS f
