Scientific paper

We present two-dimensional spectroscopy and broad band imaging of the LINER galaxy NGC 1672. The velocity field and morphology of the central 2kpc indicate higher mass concentration than in normal spirals, offsets between the nuclear continuum baricenter and the kinematical center, and between both and the cente r of the bar. Satoh's model fit to the velocity field reveals non-axisymmetric residuals, not well correlated with the bar or the circumnuclear ring of HII regions. The inner rotation curve locates the ring of star formation on an ILR, and not near the peak of Ω-κ/{2}, as suggested by previous works, also claiming the ring rotating faster than its ambient, result not confirmed h ere.
