摘要：
2 mum spectroscopic observations by many authors have revealed significant rotation-vibrational H-2 emission is widespread from starburst to bare nucleus galaxies. Near-IR H-2 emission lines can arise from various excitation sources: UV radiation by hot stars, shock excitation by supernova remnants or AGN driven winds, and UV/X-ray radiation by an AGN. In this review recent data will be compared with such H-2 excitation models.
