Scientific paper

We present mid-infrared spectra of various hydrocarbons toward the hot core associated with the massive protostar NGC 7538 IRS 1. Because high abundances of fully hydrogenated molecules and saturated molecules are characteristic of hot cores, they provide laboratories in which to study interstellar chemistry. Through the study of C[2]H[2], HCN, NH[3], CH[4], and CH[3], we can constrain chemical models. We derive abundances for C[2]H[2] and HCN and compare to model predictions. The observations were taken with the Texas Echelon Cross Echelle Spectrograph (TEXES).
