It is well known that Raman scattering process exists in symbiotic star. In this thesis we adopted a Raman scattering model in symbiotic star which had been proposed by Lee ＆ Hyung(2000) and calculated the Raman scattered O VI doublet photon flux from the ORFEUS-BEFS data. With this result we argued the validity of the assumed Raman scattering model and suggested some modifications to that model. And finally using the ORFEUS-BEFS data and the assumed scattering model we predicted the profile and strength of Hα wing which is formed by the Raman scattering of near-Lyβ continuum photon with $N(HI)=10^{21} cm^{-2}$.
