Scientific paper

1-5 micron observations for 66 compact H II regions are presented and combined with existing FIR and submm data from 12-100 microns. The total spectra are interpreted in terms of dust emission; radiative transfer calculations indicate that in all regions the exciting stars are surrounded by a cavity of very low dust density. The total energy output of the H II regions places them among the most luminous sources in the Galaxy. A strong relation is found between luminosity and gas mass yielding a star formation efficiency of 8 percent.
