The authors have obtained near-infrared spectrophotometry of three objects in the SMC and seven in the LMC, all listed as compact Hα emission line objects. They also observed a position in one of the two main ionization fronts of 30 Doradus. Three objects did not show Brackett-γ emission und thus do not appear to be H II regions. The 30 Doradus position showed He I and Br γ emission, but no H2 emission. In six of the remaining objects, H2 emission was also searched for. It was detected in three cases, and possibly in two more. Analysis of the observations shows that the molecular hydrogen emission may be caused either by shock excitation due to stars embedded in a molecular cloud or by fluorescence of molecular material in the ultraviolet radiation field of the OB stars exciting the H II region. The molecular hydrogen associated with N88 is at least in part shock-excited.
