We present preliminary results for late-type barred spiral galaxies observed with SpIOMM, an imaging Fourier transform spectrometer at the Observatoire du Mont-Mégantic with a 12' x 12' field of view. Using the emission lines, we describe the HII region characteristics: their young star populations (age and mass) and the associated ionized gas (abundance and extinction). These data will be used to study the role of the bar in the gas flow and compression into new star-forming regions, a mechanism often proposed to pace the evolution of galaxies.
