Molecular Force Fields Of Ethylene, Allene, Formaldehyde, Ketene, And Diazomethane, Charles Edward Bailey Mar 1959

Molecular Force Fields Of Ethylene, Allene, Formaldehyde, Ketene, And Diazomethane, Charles Edward Bailey

Doctoral Dissertations

Infrared and Raman spectra furnish one of the most powerful methods for studying the internal forces which act in molecules. The vibrational frequencies which are obtained from a study of the spectra are functions of the geometry and masses, which determine the kinetic energy of the system, and of the forces acting in the molecule, which determine the potential energy of the system. Therefore, if the geometry of a molecule is known, the vibrational frequencies of the molecule can be used to ob­tain information concerning the forces acting during the motions.

Doctoral Dissertations

Introduction: Medicinal chemistry is one of the areas of scientific endeavor which has been achieving increasing importance during the last two decades. It tends to become more and more the study of the chemical reactions between therapeutic agents and living tissues. In 1940 practically nothing was known about the processes by which drugs produce their effect, how they react with protoplasm and how they are in turn modified, detoxified, metabolized, or eliminated by living organisms. Appreciable progress in this direction is now being made.

Recent advances in such a field are by no means defined. Countless drugs have been introduced …


On Linear Associative Algebras Corresponding To Association Schemes Of Partially Balanced Designs, R. C. Bose, Dale M. Mesner Mar 1959

On Linear Associative Algebras Corresponding To Association Schemes Of Partially Balanced Designs, R. C. Bose, Dale M. Mesner

Department of Mathematics: Faculty Publications

Given v objects 1, 2, .. , v, a relation satisfying the following conditions is said to be an association scheme with m classes:
(a) Any two objects are either 1st, or 2nd, . . ,or mth associates, the relation of association being symmetrical, i.e., if the object α is the ith associate of the object β, then β is the ith associate of α.
(b) Each object a has ni ith associates, the number ni being independent of α.
(c) If any two objects α and β are ith associates, then …
