Two forms of amorphous solid water reported
The structure of solid water has intrigued physicists and chemists since the nineteenth century. By now it is known that solid water has at least eight crystalline forms. In 1935 E. F. Burton and W. F. Oliver (University of Toronto) reported seeing an amorphous form of solid water, and since then a few other experimenters have said they had observed it. Now Stuart Rice (University of Chicago) and his collaborators have done careful, quantitative x‐ray diffraction, neutron diffraction and Raman‐scattering studies of water prepared in two different ways, and they believe they have observed two distinct forms of amorphous solid water.
