Spectral lines of HOCH₂CN in the PILS spectrum towards IRAS 16293B at the half-beam offset position. The observed spectrum is plotted in black, with synthetic spectra overplotted (N_T = [3.0 × 10¹⁵] cm⁻², T_ex = 150, blue, and 300 K, red). All covered transitions with A_ij ≥ 1.0 × 10⁻³ s⁻¹ that are not blended are shown. The transition is indicated at the top of each panel and the upper state energy is given in the top left of each panel. HOCH₂CN is detected in the half-beam offset position spectrum towards IRAS 16293B.
