Abstract
By virtue of its spectrometers having simultaneous multichannel integration capability and relatively large input apertures, the International Ultraviolet Explorer satellite has been the first instrument capable of effective study of the ultraviolet spectra of the gas from extended H ii regions. This review will concentrate on discussing the results of the studies made of the ultraviolet emission line and continuum spectra of the gas and dust of extended H ii regions in the Galaxy and the Magellanic Clouds. However, it should be noted also that ultraviolet spectral studies with the IUE have contributed new information about the extinction and dust associated with H ii regions, the nature of the highly ionized gas surrounding their exciting stars via ultraviolet absorption lines, and the integrated stellar + nebular spectra of more distant extragalactic H ii regions. Since the latter three subjects are parts of other reviews in this book, herein we will limit our discussion to results related to the continuous and emission line ultraviolet spectra from the gas and dust within the H ii regions themselves.
