PEG의 라만 데이터 좀 알려주세요..라만 peak이 어떻게 나오나요??
  • PEG
  • Raman

    >PEG의 라만 데이터 좀 알려주세요..라만 peak이 어떻게 나오나요?? 다음 paper를 참고 하시면 될 것 같습니다. Journal of Polymer Science Part A-2: Polymer Physics Volume 8, Issue 10 , Pages 1787 - 1796 Title : Raman spectra of poly(ethylene glycols) in solution J. L. Koenig, A. C. Angood Division of Macromolecular Science, Case Western Reserve University, Cleveland, Ohio 44106 Abstract Raman spectra have been obtained from poly(ethylene glycol) (PEG) in the solid and molten phases and in aqueous and chloroform solutions. Several new lines are observed or resolved in the Raman spectrum of the solid state as a result of using a high-power argon-ion laser as a source. The Raman spectra of the molten polymer and the chloroform solutions are indicative of a disordered structure, since additional Raman lines appear as a result of the additional rotational isomers. The Raman spectrum of the aqueous solution shows that considerably less structural change occurs upon dissolution in water.

    sorilove 님께서 올려주신 reference 의 url 입니다. 저는 받을 수 없군요. '자료요청'란에 요청하시면 구하실 수 있을 것 같습니다. 그리고, 찾은 다른 reference 를 하나 더 올립니다. 참고하시기 바랍니다.
