We have obtained a series of high resolution optical spectra of the symbiotic system CD . We derive the radial velocity curve of the cool component and determine an orbital period of about 1448 days and a mass function of for this binary.
We present line profiles of H and the Raman scattered line at 6825 for various orbital phases. The H line shows very strong variations in flux and spectroscopic structure which are locked to the orbital phase. Much less variability is seen in the Raman scattered line.
