Our knowledge of free radicals and atoms has increased rapidly during the past decade through the use of new techniques. Atoms and free radicals have been detected spectroscopically in the gas phase by vacuum ultraviolet absorption (1,2), and by emission…

Starch xanthates were first prepared over 50 years ago, and since then little has been learned about their chemical structure; even suggestions for their industrial utilization have been very few. In the meantime, the emergence of the viscose process and…

For purposes of mechanistic study and structural assignment in organic chemistry it is often of great practical value to possess some knowledge concerning the basic strengths of various functional groups. The present work will concern itself primarily with a study…

Our present knowledge of nuclear structure attempts to explain nuclear properties on the basis of nucleons resonating as protons and neutrons with very strong, short-range forces acting between them. The nature of the forces between these elementary particles are not…

Bonds are broken and formed in all chemical reactions. A knowledge of the dissociation energies of the relevant bonds helps one to predict the ease by which a given reaction may take place. It is obvious, therefore, that such information…

Chemical changes involve the breaking of bonds in the reacting molecules and the formation of bonds in the products; they are usually accompanied by energy changes. Although the stability of a molecule or a radical, as expressed in terms of…

Chemical reactions involve ordinarily the breaking of bonds in the reacting molecules and the formation of bonds in the products; they are usually accompanied by changes in enthalpy. Although the stability of a molecule or a radical, as expressed in…

It is now generally recognized that the processes involved in a chemical reaction are frequently not as simple as the stoichiometric equation would indicate, but consist rather of a series of elementary reactions of simple order; the over-all reaction observed…

The potentialities of catalysis were foreseen by Ostwald when he prophesied that a scientific knowledge and control of catalytic phenomena would lead to immeasurable results technically (1). This prophecy has been fulfilled, for to-day the importance of catalysis in science…

The seed hairs of the typha family (cat-tails) are easy to collect and appear to the eye to consist of cellulosic fibers of nearly uniform length radiating from a central stem. The object of the present Thesis was to review…
