Abstract: We discuss the results of infrared spectroscopy of pure rotational lines of H_2, as well as several fine-structure lines for two embedded intermediate-mass Young Stellar Objects (YSO's): S106 IR and Cep A East. H_2 excitation temperatures and masses are 490 and 740 K and 0.04 and 0.007 Msun for S106 and Cep A, respectively. The bulk of the H_2 (several Msun are expected) must be cooler than a few hundred Kelvin. We conclude that the infrared spectrum of S106 IR is dominated by PDR emission while that of Cep A East has a large shock component.
