In a comparative study, optical and radio spectra are presented in order to further investigate violent turbulent motions in starburst galaxies. Emission-line, HI and OH profiles of IRAS 10039-3338 exhibit signs of a highly perturbed far-infrared galaxy. Remarkably narrow and distinct OH components are shown in the megamaser spectra. A molecular mass of 1010 MO is deduced from CO observations. The presence of comparable numbers of blue and red-shifted components is apparently not in favor of an outflow interpretation.
