We present scanning Fabry-Perot interferometric observations of CIG 993, anapparently isolated luminous infrared galaxy also exhibiting luminous bluecompact and Wolf-Rayet galaxy features, as well as high star formation rate.Our high resolution observations of the H$\alpha$ emission line allowed us toderive the radial velocity field, as well as the velocity dispersion $\sigma$,and the residual velocity fields of the galaxy. This galaxy exhibits severalkinematical components. On one hand, the velocity gradients detected on thevelocity field can be associated with a rotating disk -contrary to previousresults with less spectral resolution-. However, the velocity field, the$\sigma$ and residual velocity field show significant deviations from circularmotions in the central part of the galaxy that matches a region with highnumber of Wolf-Rayet and O stars, coincident with the blue luminous componentof the galaxy. We find narrow and broad velocity components for the ionized gasin the central part of the galaxy. The broad component is evidence of a centraloutflow related with the on-going burst of stellar formation. Themorpho-kinematical analysis of the galaxy indicates we are only seeing thebrightest parts of the galaxy which correspond to the bulge, a central bar andthe beginning of the disk. We believe CIG 993 is a disk galaxy harboringimportant star-forming processes most likely caused by a relatively recentinteraction. This could imply that small encounters could change the globalcharacteristics of a galaxy without disturbing the main rotation disk motion,nor the morphology of the galaxy.
