UZ Oph, TT Oph and AD Aql are classified as RV Tauri stars in the General Catalog of Variable Stars. We present preliminary results of our study of the spectral variations of these stars including observations from 2003 to the present. Changes on the order of several spectral types and luminosity classes are observed. We discuss each object's shift in position on the L vs. T diagram as a function of the phase of their light curve. Our photometric data is taken from the AAVSO International Database and our spectra come from a long term observing program organized by S. Howell using the Coude Feed Telescope at Kitt Peak National Observatory. Support for this work was provided by the NSF PAARE program to South Carolina State University under award AST-0750814. We thank the director of KPNO for his generous allocation of telescope time to this project over the years.
