A Quote by Derek Harold Richard Barton
X-Ray crystallography is nowadays an accurate and rapid method of determining conformation in the crystal lattice, which conformation usually corresponds to the preferred conformation in solution.

If we possessed a thorough knowledge of all the parts of the seed of any animal (e.g. man), we could from that alone, be reasons entirely mathematical and certain, deduce the whole conformation and figure of each of its members, and, conversely if we knew several peculiarities of this conformation, we would from those deduce the nature of its seed.
If the polymer chain assumes a helicoidal conformation in the crystalline state, and if it does not contain asymmetric carbon atoms, it can be expected that either helices of the same sense, or, in equal ratio, helices of opposite sense are represented in the lattice.
Expediency therefore concurs with Nature in stamping the seal of its approval upon Regularity of conformation.
The truly great rest in the knowledge of their own deserts, nor seek the conformation of the world.
Conformation ... but not much else. Breeding, but too small a heart. You saw it everywhere - in men, in horses, and in women.
Poetry demands a different material than prose. It uses another facet of the same fact... the spontaneous conformation of language as it is heard.
Until you have bred dogs and have drawn and painted them, it is difficult to realize that no two are identical in conformation. You need do no more than gun for a day over two of them to recognize that each is an individual. It requires the intimacy of daily living with a dog to know the subtle quality of his mind, the ham-smell of his ears, and that his wet nose in your mouth tastes salty.
The conformation of his mind was such that whatever was little seemed to him great, and whatever was great seemed to him little.
Human beings are not like sheep; and even sheep are not undistinguishably alike. A man cannot get a coat or a pair oboots to fit him, unless they are either made to his measure, or he has a whole warehouseful to choose from: and is it easier to fit him with a life than with a coat, or are human beings more like one another in their whole physical and spiritual conformation than in the shape of their feet? If it were only that people have diversities of taste, that is reason enough for not attempting to shape them all after one model.
The present rate of progress [in X-ray crystallography] is determined, not so much by the lack of problems to investigate or the limited power of X-ray analysis, as by the restricted number of investigators who have had a training in the technique of the new science, and by the time it naturally takes for its scientific and technical importance to become widely appreciated.
If the chain symmetry is maintained in the crystal lattice, the possible occurrence of different space groups is considerably restricted.
The structure of many cellular macromolecules has been revealed at the atomic level using x-ray crystallography.
Capitalism in its imperialistic stage is a system which regards war as a legitimate method for solution of international disputes - a method which is legitimate in fact if not legally so.
A delicate, inexorable lattice of inferences began to assemble themselves, like a crystal, in the old man's mind, shivering, catching the light in glints and surmises.
In particular, I established a reasonably accurate energy threshold for permanent displacement of a nucleus from its regular lattice position, substantially smaller than had been previously presumed.
Suppose that the organism is given the problem of determining the analysis of a stimulus at a certain level of representation - e.g., the problem of determining which sequence of words a given utterance encodes. Since, in the general case, transducer outputs underdetermine perceptual analyses, we can think of the solution of such problems as involving processes of nondemonstrative inference. In particular, we can think of each input system as a computational mechanism which projects and confirms a certain class of hyputheses on the basis of a certain body of data.
