We highlight first results from the VIRUS-P Investigation of the eXtreme ENvironments of Starbursts (VIXENS) integral field unit survey. We investigate the relationship between star formation and gas content in late interaction phase merger Arp 299 from VIXENS. By comparing Hα, Paα, and 24μm images to CO(2→1), CO(3→2), HCN(1→0), HCO+(1→0), and HI maps, we explore the relation between the star formation rate and gas surface densities on spatially resolved ~kpc scales. We find that the SFR-gas relations for Arp 299 are discrepant from known extragalactic spatially resolved relations in nearby spiral galaxies and disk-averaged relations in high-z mergers.
