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
