We present neutral hydrogen (H{\sc i}) observations with the Giant Metrewave Radio Telescope ({\it GMRT}) of the interacting galaxies NGC5996 and NGC5994, which make up the Arp72 system. Arp72 is an M51-type system and shows a complex distribution of H{\sc i} tails and a bridge due to tidal interactions. H{\sc i} column densities ranging from 0.8$-1.8\times10^{20}$ atoms cm$^{-2}$ in the eastern tidal tail to 1.7$-2\times10^{21}$ atoms cm$^{-2}$ in the bridge connecting the two galaxies, are…
