Abstract
The authors have obtained ultraviolet spectrophotometry of five isolated galaxies with the IUE which confirms the existence of the ultraviolet excesses first found by UBV photometry. Observations from the optical part of the spectrum to the radio bands are combined with the ultraviolet data to explain the nature of the UV excesses as the signature of a young stellar population in addition to that normally observed in nuclei of galaxies.
