Intense star formation (SF) and starbursts (SBs) manifest themselves in emission-line spectra. Although merging and interactions are widely accepted as a trigger for SBs, it is still unclear to what extent these factors play a role and what other aspects are important. Measuring the internal motions in galaxies can, in combination with other diagnostics, contribute to our understanding of SB triggers. Here, we present recent observations of a complete sample of emission-line galaxies, using the Hα emission line to determine the internal dynamics of the targets. Masses are estimated, assuming Keplerian motions.
