I first met the subject of X-ray diffraction of crystals in the pages of the book W. H. Bragg wrote for school children in 1925, 'Concerning the Nature of Things.'
The detailed geometry of the coenzyme molecule as a whole is fascinating in its complexity.
I should not like to leave an impression that all structural problems can be settled by X-ray analysis or that all crystal structures are easy to solve. I seem to have spent much more of my life not solving structures than solving them.
