High-dispersion spectroscopic observations with good spectral resolution have been made of the four clumps in the two clumpy irregular galaxies Markarian 297 and 325. Their velocity dispersions in the Hα emission line (32-41 km s−1) are larger by about 2 or more than those of the so-called giant HII regions in nearby spiral or irregular galaxies.
