In the context of the collaboration of several European observatories, we are examining a number of eclipsing binary systems in search for evidence of pulsation phenomena. We hope our candidate systems will be suitable for subsequent asteroseismological studies. Here we present a preliminary radial velocity curve analysis of three such binaries: RX Her, HS Her and V994 Her, with estimations of mass ratios and orbital elements. The spectroscopic observations were made at National Astronomical Observatory Rozhen, Bulgaria, in the period from 2002 to 2005, making for good phase coverage of the selected objects. Reduction and analysis were done at Astronomical Observatory of Belgrade, Serbia.
