The variety of molecular megamasers trace different classes of galaxies and provide information on their various nuclear components. H2O megamaser regions may trace the inner parsec-scale regions with keplerian disks of the LINER and Seyfert 2 nuclei, which are relatively naked and not dominated by dust or starforming regions. The OH and H2CO megamaser emissions exhibit the physics and dynamics of the inner few hundred parsecs of ultra-luminous FIR galaxies, which are dusty, compact, and whose perturbed nuclei are powered by compact starbursts.
