本文对TiO2的同质多象变体：金红石、锐钛矿、板钛矿和铌铁矿结构型TiO2-Ⅱ分别进行了群论分析，并对实测拉曼光谱进行了归属讨论。
In this paper , the TiO_2 polymorphs : rutile , anatase , brookite and columbite-type TiO_2 - ⅱ were analysed respectively according to the group theories , and the Raman spectra of these phases measured at ambient conditions were discussed for their assigment .
