Abstract. The results from the H I 21 cm-line imaging of a few isolated Wolf-Rayet (WR) galaxies using GMRT will be presented. WR galaxies have substantial population of very massive young stars therefore tracing very recent (∼ 106 yr) star formation event in a galaxy. The WR galaxies can provide clues on mechanisms related to star formation trigger in galaxies. The selected WR galaxies in the present study do not have known optical companion or any remarkable optical distortion. We find that in most of the cases H I tidal tails can be traced in these galaxies indicating tidal origin of WR phase. The main results and GMRT images will be presented.
