测量了PbO ·xSiO_2玻璃的偏振拉曼光谱和红外粉末吸收光谱，并从玻璃结构的角度进行了解释。还将玻璃的光谱与许多稳定和亚稳晶相的光谱进行了比较。发现玻璃由许多硅酸盐物质组成。在x小于1的玻璃中，可以从光谱中可靠地推断出离子氧（不与硅键合的氧）的存在。本文还报道了一种新的谱线去卷积方法。
The polarized Raman spectra and infrared powder absorption spectra for PbO ·xSiO2 glasses, with 0.5⩽x⩽2, were measured and interpreted in terms of the structure of the glasses. Comparison of the spectra of the glasses with the spectra of numerous stable and metastable crystalline phases was also made. It was found that the glasses are composed of a number of silicate species. In glasses for whichx is less than 1, the presence of ionic oxygen (oxygen not bonded to silicon) is confidently inferred from the spectra. A new way of deconvoluting the spectra is also reported.
