Abstract
The anisotropic Raman scattering properties of oriented syndiotactic poly propylene have been investigated using FT-Raman spectrometer in which the fluore scent problem of polymer samples can be removed. To assign the observed Raman bands to their respective symmetry species, the anisotropic scattering results for four different combinations of incident and scattered polarization were compared with those predicted by normal cooridinate anaylsis and infrared dichroism measurement data.

본 연구에서는 시료의 형광문제를 제거한 FT-Raman spectrometer를 이용하여 연신된 syndiotactic polypropylene의 비등방적 Raman 산란 특성을 측정하였다. 관찰된 Raman 피크를 해석하여 해당 symmetry species 분류를 목적으로, 입사 및 산란 복사선의 편광방향이 서로 다른 4 가지 편광실험을 수행하여 스펙트럼을 얻었다. 이 편광 Raman 실험 결과를 편광 infrared 실험에 의한 dichroism 결과 및 진동운동의 이론적 계산인 normal coordinate analysis 결과와 비교분석하였다.

Keywords: polarized Raman; syndiotactic polypropylene; symmetry species; chain conformation
