本文综述了冰光谱的实验和理论研究工作。它在射频区的特征来自于水分子在晶格位置的重新取向，在晶格位置处，分子振动的强热激发产生缺陷。冰的大介电常数和弛豫时间与我们对其结构的认识是一致的。微波区域的研究不太广泛，但有足够的信息可以确定冰中水分子的分子极化率如何取决于温度和体积。在红外区，两个功能，所产生的平移晶格振动和对称O-H伸缩，受到了很大的关注，并正在取得进展，对它们的理论理解。可见光区和紫外区没有明显的特征，在这一区域的吸收率很小。当然，冰的整个光谱对于许多自然现象的研究都是有用的，但是辐射中的特征...
Abstract This article reviews experimental and theoretical work on the spectrum of ice. Its features in the radiofrequency region arise from the reorientation of water molecules at lattice sites where strong thermal excitations of a molecular vibration produce a defect. The large permittivity and relaxation time in ice are consistent with our knowledge of its structure. The microwave region has been less extensively studied, but enough information is available to determine how the molecular polarizability of a water molecule in ice depends upon temperature and volume. In the infrared region, two features, arising from the translational lattice vibrations and symmetric O-H stretching, have received much attention, and progress is being made towards understanding them theoretically. The visible and ultraviolet regions show no distinctive features, and the absorptivity in this region is small. The entire spectrum of ice is, of course, useful for studies of many natural phenomena, but the features in the radi...
