Abstract: The relationship between star formation rate (SFR) and the interstellar gas surface density (Σgas) is fundamental to galaxy evolution. To achieve physical understanding of this relationship, it is necessary to study the detailed star formation properties of giant molecular clouds (GMCs). Here we report preliminary results of the case study of W31 and W43, two obscured starburst regions in the Milky Way. We have used IR spectroscopic observations to determine the type and nature of luminous sources in these two regions. Progressions of massive star formation are seen in both W31 and W43. We will extend this work to more starbursts associated with GMCs and aim at assessing the SFR-Σgas relation in the Galaxy.
