Description
We present very deep spectrophotometry of 14 bright extragalactic HII regions belonging to spiral, irregular, and blue compact galaxies. The data for 13 objects were taken with the High Resolution Echelle Spectrometer on the Keck I telescope. We have measured CII recombination lines in 10 of the objects and OII recombination lines in eight of them. We have determined electron temperatures from line ratios of several ions, especially those of low ionization potential.
