We will study the morphologies and star formation rates of a representative sample of 19 IR-selected starburst galaxies. We propose to obtain broad band UBVRIJHK images with the KPNO-2.1m telescope and for most of the sample, optical (R~ 1200) and HK spectra (R~700). We will then measure structural parameters (surface brightness profile, metric radius, asymmetry and concentration indices, and degree of flocculency) and spectroscopic lines (H(alpha), [NII], [OIII] in the optical, and Br(gamma), CO bands, [FeII], H_2 in the near infrared) to address the relationship between morphology and star formation rate. The optical 2-D spectra with DensePak will allow us to study the distribution of star-forming sites within the central regions of the galaxies. The H and K spectra with ONIS at the KPNO-4m telescope will allow us to penetrate regions obscured by dust and study their spatial distribution along the major axis. Together these imaging and spectroscopic data will constitute the basis for comparisons of galaxy populations at high redshifts with imaging spectrographs on 8m class telescopes. All data will be made available to the community.
