Abstract We propose to obtain high S/N spectra of 3 AGNs noted for their strong optical Fe II emission, in order to study the properties of the Fe II UV multiplets in the 2000- 3000 A range. This study builds on our development of a unique empirical technique for determining the strength and velocity profile of Fe II based on a template constructed from one of the proposed objects, I Zwicky 1. Our analysis will allow an accurate measure of the relative strengths and profile widths of the UV and optical multiplets, testing for saturation of the UV multiplets and estimating relative contributions of collisional excitation, X-ray heating and fluorescence. The total Fe II cooling rate will yield a better estimate of the BLR covering factor. The Fe II emission can then be subtracted, allowing measurement of the Mg II profile and those of weaker features such as C II\] 2325. A clean determination of the continuum allows more sensitive searches for Mg II doublets in absorption and the strength of any 2175 A dust feature. The narrow lines of I Zw 1 and PG 1404+226 will enable us to identify the individual lines of the multiplets and compare an object with \[Fe II\] to one without. A comparison of the Mg II and H beta profiles will constrain the relative geometry and kinematics of the BLR cloud distribution for the two species. PG 0804+761 shows much stronger emission in multiplet 42, prompting a search for other anomalies. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.
