Excerpt from The Absorption Spectra of Solutions, of Comparatively Rare Salts: Including Those of Gadolinium, Dysprosium, and Samarium, the Spectrophotography of Certain Chemical Reactions and the Effect of High Temperature on the Absorption Spectra, of Non-Aqueous Solutions
During the last decade a considerable number of physicists have directed their efforts towards solving some of the many problems of spectroscopy. The following chapter will contain a discussion of some of this work, with the view of recording part of our experimental knowledge concerning the nature of the emission and absorption centers of light; the connection between these centers and molecular and atomic structures; the effect of ionization and recombina tion on these centers, and the effects and changes that can be produced by physical and chemical agents such as temperature, the presence of a mag netic field, etc., upon the constitution of the emission and absorption centers.
Emission and absorption centers will be defined as the smallest particles from which we can obtain characteristic absorption or emission spectra. A further division of the centers of any characteristic spectrum would make it impossible to obtain that spectrum, though the resultant particles may possess characteristic absorption or emission spectra of their own. When emission or absorption centers move with reference to an observer, the frequencies of the spectral lines and bands will show the Doppler effect.

Paperback. Zustand: New. Print on Demand. This book discusses the absorption and emission centers of light and heat, with a focus on atomic structure, the ionization theory, and chemical reactions, and the effect of temperature on absorption spectra. It also explores the connection between emission and absorption centers and the chemistry of the centers. The author considers various theories and experiments, including the work of Stark, Lenard, and others. The text provides a detailed overview of the field, examining the nature and velocity of particles in sparks that are acting as absorption and emission centers of line spectra. The author investigates the emission centers of flames and arcs, the Zeeman effect, and the possible catalytic action of light. An exploration of the emission spectra of organic compounds and the absorption spectra of various salts in solution, as well as the influence of the solvent, is also included. This book offers a comprehensive analysis of the absorption and emission spectra of various substances, making it a valuable resource for scientists and researchers in the field.
