Abstract
THE present volume is designed as a continuation of the work of Jones and Uhler and Jones and Anderson, and gives the results of a detailed study of the absorption spectra of salts of potassium, cobalt, nickel, copper, chromium, erbium, praseodymium, neodymium, and uranium, as affected by various chemical reagents and different temperatures. For the purpose of the discussion some 3000 solutions have been examined. The main points of investigation have been the effects of the addition of free acids and foreign salts on the absorption spectra. A notable result is the discovery of well-defined “solvent bands” for various substances, for example, water, alcohols, acetone, glycerol, which do not show any appreciable absorption of visible light.
