OH伸缩基频和第一、第二和第三OH泛音振动已经用纯的和掺GeO_2的渐变折射率的熔融石英光纤（OH含量从小于1ppm到大于1，000 ppm）进行了检验。先前报道的熔融石英基本振动的组分子结构。几个新的振动被发现和分配。氘代OH样品的检查有助于验证任务。由GeO2产生的光谱增宽被解释在更广泛的环境中看到的OH振荡器，相比纯熔融石英。
The OH-stretching fundamental, and the first, second, and third OH overtone vibrations have been examined using pure and GeO2 - doped graded index, fused silica optical fibers having OH contents from less than 1ppm to greater than 1,000 ppm. The previously reported component substructure of the fundamental vibrations of fused silica. Several new vibrations were uncovered and assigned. Examinations of deuterated OH samples helped to verify the assignments. The spectral broadening produced by GeO2 was interpreted in terms of a wider range of environments seen by the OH oscillators, compared to pure fused silica.
