We performed a spectral-line survey toward the three positions, an outflow shocked region, OMC2-FIR 4, in addition to the driving source of the molecular outflow, FIR 3, and the northern outflow lobe, FIR 3N, with the Nobeyama 45 m and ASTE telescopes. We detected more than 100 molecular lines. We found that the line profiles can be classified into the following two types: a single Gaussian component with a narrow (< 3 km s(-1)) velocity width and two Gaussian components with narrow and wide (> 3 km s(-1)) velocity widths. The wide components of CO, CS, HCO+, and HCN are also detected at three positions including FIR 3N, suggesting that these trace the molecular outflow. On the other hand, the wide components of SiO, SO, (CS)-S-34, CH3OH, (HCN)-C-13, and (HCN)-C-15 isotopes are detected only at the outflow shocked region, FIR 4, suggesting that these trace the outflow-shocked gas. In addition, the rotation diagram analysis revealed that the narrow components in both the two profile types correspond to the gas with a low temperature of 20-30 K, while the wide components trace a high temperature of 50-150 K. These results support our interpretation that the wide velocity components trace the molecular outflow and/or outflow-shocked gas.
