Van Dishoeck Física, Astronomía y Matemáticas ISM: Clouds ISM: Molecules ISM: Abundances 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 C2H2, HCN, NH3, CH4, and CH3, we can constrain chemical models. We derive abundances for C2H2 and HCN and compare to model predictions.
