Scientific paper

Evidence is presented that the emission spectra and radio structures of low-redshift quasars are related statistically. The sample comprises 34 quasars with z less than 0.70 and known radio structures. Objects with the broadest and most irregular emission lines are associated with extended radio sources, while those with relatively narrow emission lines with smooth profiles tend to have compact radio structures. There is also a significant tendency for Fe II emission lines to be found preferentially in quasars with compact radio structure.
