   I know that in spectroscopic Binaries, you can observe wavelength shifts in each star. But how do you determine the total radial velocity of this system alltogether, and how do you find each star's radial velocity?

   You can determine the radial velocity of a particular star based on the wavelength of light, since a specific speed corresponds to a specific level of red/blue shift.
