超低频拉曼光谱可以测量低至±10 cm−1 的振动带，可以轻松地对多晶微结构（例如具有高多晶型特异性的晶粒和晶界）进行原位成像。我们通过使用显微镜研究 1,1'-联萘的两种不同多晶型物的微晶来演示该方法。
Ultralow-frequency Raman spectroscopy that can measure vibrational bands at as low as ±10 cm−1 has enabled facile in situ imaging of polycrystalline microstructures such as grains and grain boundaries with high polymorph specificity. We demonstrate this method by investigating microcrystals of two distinct polymorphs of 1,1′-binaphthyl using a microscope.
