Using the Short-Wavelength-Spectrometer on the Infrared Space Observatory (ISO), we obtained nearand midinfrared spectra toward the brightest H2 emission peak of the Orion OMC-1 outflow. A wealth of emission and absorption features were detected, dominated by 56 H2 ro-vibrational and pure rotational lines reaching from H2 0–0 S(1) to 0–0 S(25). The spectra also show a number of H i recombinatio...
