报告了在 80 kbar 静水压力和 155 kbar 非静水压力下金红石晶体的拉曼光谱。 35 kbar 附近的光谱变化（之前根据向 TiO2II 的转变进行解释）显示出代表低压下非常非谐波材料的光谱与压力大于 50 kbar 下相对谐波材料的光谱之间的中间情况。
Raman spectra of rutile crystals under hydrostatic pressures to 80 kbar and non‐hydrostatic stresses to 155 kbar are reported. Spectral changes near 35 kbar, previously interpreted in terms of a transformation to TiO2II, are shown to represent an intermediate case between the spectra of a very anharmonic material at low pressures and a relatively harmonic material at pressures greater than 50 kbar.
