The First Mid-infrared Detection of HNC in the Interstellar Medium: Probing the Extreme Environment toward the Orion Hot Core
Abstract We present the first mid-infrared (MIR) detections of HNC and <?CDATA ${{\rm{H}}}^{13}\mathrm{CN}$?> in the interstellar medium, and numerous resolved HCN rovibrational transitions. Our observations span 12.8–22.9 μ m toward the hot core Orion IRc2, obtained with the Echelon-Cross-Echelle Spectrograph aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA). In particular, …
