(James A. Ibers et al., "Proton magnetic resonance...)

**f appeared to be well suited for the study of these matters , since it is a normal paramagnet , with three unpaired electrons on the chromium , its crystal structure is very simple , and the unknown position of the hydrogen in the strong **f bond provides structural interest .

Douglass has studied the crystal structure of **f by x-ray_diffraction .

The measured powder density of the **f used here was about **f , approximately one-third that of the crystal density ( **f ) .

(Robert Heinlein, Stranger in a Strange Land....)

But he was looking_forward to snow - seeing for himself that each tiny crystal of the water of life was a unique individual , as he had read - walking barefoot , rolling in it .
