Description
A good linear correlation is found between the H2 v = 1-0 S(1)/Br-gamma and the forbidden O I 6300/H-alpha emission-line ratios on a sample of 28 galaxies containing an AGN or a starburst nucleus (SBN). In the SBNs, the observed relation between the line ratios concerned matches the relation for SNRs. Thus the dominant excitation mechanism of molecular hydrogen is shock heating. In the AGNs, X-ray heating is the dominant mechanism because the model of Lepp and McCray (1983) reasonably explains the observed correlation. 48 refs
