项目摘要

We measured the Stokes to anti-Stokes intensity ratio in the phonon Raman spectrum of a rutile (TiO2) crystal. We found that although the ratio still equals the Boltzmann factor at the center frequency of a mode, it deviates from the Boltzmann factor and approaches a constant value at the center frequency within the spectrally-broadened region. It is suggested that irreversible dissipation is essential to understanding this deviation and the broadening of the phonon mode.
我们测量了金红石(TiO2)晶体的声子拉曼光谱中的抗螺旋强度比。我们发现,尽管该比率仍然等于模式的中心频率的玻尔兹曼因子,但它偏离了玻尔兹曼因子,并在频谱宽阔区域内的中心频率下接近恒定值。建议不可逆转的耗散对于理解这种偏差和拓宽声音模式至关重要。
