Integrated OH line profiles of IIZw 096. The red and blue spectra were obtained by integrating the signals above 3σ over two OH emission regions (OH1 and OH2, see Fig. 1) from each channel image of the two EVN line observations listed in Table 1. The black spectrum is the OH profile from Arecibo observations by Baan et al. (1989). The two arrows represent the velocity of the OH 1667 MHz (left) and 1665 MHz (right) lines based on the optical redshift.
