We have obtained high S/N, high resolution profiles of the [OIII] \lambda 5007 emission line for nearly all of the PG quasars.Previous studies have shown that the kinematics of the narrow line region gas (NLR) in active galaxies are predominantly due to gravitational motion in the host bulge potential. Thus, using the now well established correlation between bulge velocity dispersion, \sigma, and nuclear black hole mass, M\bullet , we can use the widths of the [OIII] line profiles to estimate M\bullet for the entire sample. These values are independent of results from reverberation mapping techniques which rely on the assumption of Keplerian motion in the broad line region. The M\bullet values can be used to estimate the Eddington ratio, and to test the idea that L/LE is the primary influence on the group of AGN correlations known as eigenvector 1. We present the preliminary results of our analysis in this poster. This project has been supported by the Iowa Space Grant Consortium.
