Abstract Radio continuum observntions at 11 cm of seventeen optically identified nebulae from the Sharpless catalog (1959) are reported. The spectrum is plotted and a discussion of the physical nature of each source is given. The relationship between excitation parameter and spectral type is rederived on ine basis of both LTE and non-LTE model atmosphere results and is used to interpret the observations. (auth)
