Abstract: We have obtained high S/N, high resolution profiles of the [OIII] 5007 emission line for all PG quasars with z < 0.5. 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 well established correlation between bulge velocity dispersion, σ*, and nuclear black hole mass, M, we can use the widths of the [OIII] line profiles to estimate M for the entire sample. If the [OIII] kinematics are in fact virial, this technique could provide independent estimates for M from SDSS quasar spectra.
