用氩离子激光器作激发源，在室温下记录了多晶二氧化钛的金红石相和锐钛矿相的一级拉曼谱。发现高温金红石相在低于450°C的温度下稳定。锐钛矿相在750 ℃左右转变为金红石相。观察到了群论预测的所有拉曼活性基本面。
First-order Raman spectra have been recorded at room temperature for the anatase and rutile phases of polycrystalline titanium dioxide using an argon ion laser as exciter. The high-temperature rutile phase was found to be stabilized at temperatures below 450°C. Anatase transforms to rutile phase at ∼750°C. All the Raman active fundamentals predicted by group theory are observed.
