Scientific paper

Subarcsecond resolution multifrequency VLA observations of a heterogeneous collection of 15 core-dominated QSOs and AGN are presented. The integrated Faraday rotation measures of the nuclei of these objects are determined with higher angular resolution than previously available. This reduces the effects of confusion by polarized extended emission near the core. Upper limits to the RMs of about 200 rad/sq m, higher than previous values but still much lower than the 200,000 rad/sq m which is 'expected', are estimated. The limits are consistent with the hypothesis that the emission line clouds are not confined by a thermal gas. The observations are consistent with magnetic confinement of the emission line clouds only if the field is extremely disordered or if the electron density or pathlength in the intercloud region has been severely overestimated.
