摘要

低频拉曼波段表征纤维蛋白（角蛋白）二级结构元素的振动。对未着色的人类头发进行了两种配置的实验：激发辐射同轴聚焦在头发上和垂直于头发。根据偏振灵敏度，在150和221 cm−1处的波段归因于角蛋白α-螺旋结构的振动。270 ~ 340 cm−1的光谱区间归因于β-结构的振动。

Low-Frequency Raman Spectroscopy of Human Hair Keratins

Low-frequency Raman bands characterizing vibrations of elements of the secondary structure of fibrillar proteins (keratins) are identified. Experiments with unpigmented human hair are performed in two configurations: with excitation radiation focused coaxially on the hair and perpendicular to it. Based on the sensitivity of polarization, the bands at 150 and 221 cm⁻¹ are attributed to vibrations of the α-helical structures of keratins. The spectral interval of 270–340 cm⁻¹ is attributed to vibrations of β-structures.
