FIGURE 316. William H. Bragg and his son William L. Bragg reversed von Laue s experiment and used x-rays to measure the distances between ions or atoms in crystals (see text), (a) Depicts the conditions for constructive interference of x-rays termed Braggs Law (b) schematic of Braggs s x-ray apparatus (WH.

MLH - Well, that was very simple. About the same time as I was thinking about hydrogen bonds and some other structural problems, I saw a book in the library, Bragg and Bragg s "X-rays and Crystal Structure". I felt this was fine. This book tells me what is known about the arrangements of atoms in various crystals. That should be a good way to test my theory or my modification of Lewis theory, because the same ideas of valence and chemical bonds should be applicable to the solid state as well as to individual simple molecules. I found that this theory worked perfectly for...
