In the first example the actual chemistry is identical an aldose-ketose interconversion. Note that the geometry of the alcohol on C-2 is identical. The second example has essentially the same chemistry. Logically, to do the same chemistry, nature could have stumbled upon the same mechanism twice. 

Tire source code of the LibraryChemistryProcessCommand, which processes chemistry logic on a chemical library, is as follows. (You can have another Command object to process discrete compounds. The idea is the same.)... 

Although Cheshire does a good job applying chemistry logic on molecule structures, it has two serious drawbacks ... 

This mathematical model can serve as a basis for a variety of deductive computer programs for the solution of chemical problems6-8. From among all the possibilities, synthetic planning was chosen first — for reasons stated before — and the computer program CICLOPS (Computers in Chemistry, Logic Oriented Planning of Synthe-...

Fuzzy logic and fuzzy set theory are applied to various problems in chemistry. The applications range from component identification and spectral Hbrary search to fuzzy pattern recognition or calibrations of analytical methods. 

The experiments described in Part I have been numbered, as they form a graded series to illustrate the chief manipulative processes employed in practical organic chemistry. The experiments in Parts II-V have not been numbered, as in general a selection must be made from them. In each part of the book, the experiments have been arranged as far as possible in logical order, although occasionally (as in Part IV) this is not necessarily the order of increasing difficulty. 

The task of relating carbohydrate configurations to names requires either a world class memory or an easily recalled mnemonic A mnemonic that serves us well here was pop ularized by the husband-wife team of Lours F Fieser and Mary Fieser of Harvard Uni versity m their 1956 textbook Organic Chemistry As with many mnemonics it s not clear who actually invented it and references to this particular one appeared m the chem ical education literature before publication of the Fiesers text The mnemonic has two features (1) a system for setting down all the stereoisomeric d aldohexoses m a logical order and (2) a way to assign the correct name to each one... 

This explosion in steroid chemistry both stimulated and was aided by the development of conformational analysis (10). Many basic, physical organic chemistry principles were estabUshed as a result of the study of the logically predictable chemistry of the rigid perhydro-l,2-cyclopentenophenanthrene, steroid skeleton. 

However, theories that are based on a basis set expansion do have a serious limitation with respect to the number of electrons. Even if one considers the rapid development of computer technology, it will be virtually impossible to treat by the MO method a small system of a size typical of classical molecular simulation, say 1000 water molecules. A logical solution to such a problem would be to employ a hybrid approach in which a chemical species of interest is handled by quantum chemistry while the solvent is treated classically. 

We have attempted to relate the basics of silicone chemistry to applications where adhesion is an important property. These applications cover a vast industrial arena that does not make a review of this sort easy. Instead, we focused on the fundamental aspects of silicone physics and chemistry and related them to adhesion and adherence properties. We have attempted to use a logical structure to help the reader understand silicone adhesion. Adhesion and cohesion have been considered as they both determine the ultimate performance of an adhesive joint. 

It is also important to realize that chemistry is not a static body of knowledge as defined by the contents of a textbook. Chemistry came from somewhere and is at present heading in various specific directions. It is a living self-stimulating discipline, and we have tried to transmit this sense of growth and excitement by reference to the historical development of the subject when appropriate. The chemistry of the elements is presented in a logical and academically consistent way but is interspersed with additional material which illuminates, exemplifies, extends or otherwise enhances the chemistry being discussed.
