We present high angular resolution continuum images and molecular line spectra obtained at 345 GHz with the Submillimeter Array (SMA) toward two massive cores that lie within Infrared Dark Clouds (IRDCs): G034.43+00.24 MM1 and G024.33+00.11 MM1. Both of these cores contain bright, unresolved (?), unresolved (0farcs6; ~3000 AU) continuum emission features and emission from many complex molecular transitions, which confirm that these are hot molecular cores,
