    • Inglés
    Atlas and Tables for Emission Spectrographic Analysis of Rare Earth Elements focuses on the analysis of rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion. The book first offers information on the division of the spectra of rare earth elements and Sc and Y into three groups. The spectra of Ce, Pr, Nd, Gd, Tb, Dy, Ho, and Er have lines that, however, do not form characteristic line groups. The text underscores that in preparing the Atlas, the spectral pure-grade rare earth oxides sold by the Johnson & Matthey Co. were considered. Through the help of their spectra, the usable analysis lines and the wavelength values of the interfering spectral lines are created. The operating and photographic conditions are tabulated. The book stresses that for each rare earth, the analysis lines are provided in order of decreasing wavelength. The number located in the lower left corner for each analysis line indicates its relative intensity. The fifteen columns contain the interfering lines of other rare earths and of Sc and Y. The interfering lines are created through the use of the double projector of the Optica Milano Co. and the Gatterer Spectrum. The text is a great source of information for readers wanting to analyze rare earths with the Zeiss Q 24 spectrograph or with instruments of similar dispersion.

    Annual Reports in Organic Synthesis—1973 presents an annual review of synthetically useful information that would prove beneficial to nearly all organic chemists, both specialist and nonspecialist in synthesis. It should help relieve some of the information storage burden of the specialist and should aid the nonspecialist who is seeking help with a specific problem to become rapidly aware of recent synthetic advances. In producing this volume the editors abstracted 47 primary chemistry journals, selecting useful synthetic advances. All reactions and methods which are new, synthetically useful, and reasonably general are included. Each entry is comprised primarily of structures accompanied by very few comments. The purpose of this is to aid the reader in rapidly scanning the book. Chapters I-III are organized by reaction type and constitute the major part of the book. Chapter IV deals with methods of synthesizing heterocyclic systems. Chapter V covers the use of new protecting groups. Chapter VI is divided into three main parts and covers those synthetically useful transformations which do not fit easily into the first three chapters. The first part deals only with functional group synthesis. The second part covers ring expansion and contraction, and the third part involves useful multistep sequences.

  • Fourth International Conference on Non-Aqueous Solutions

    • V. Gutmann
    • Inglés
    Non-Aqueous Solutions is a collection of papers presented at the Fourth International Conference on the same subject. One paper presents the application of far- and mid-infra-red, Raman, alkali metal n.m.r. and 35C1 n.m.r. techniques to the study of electrolyte solutions in non-aqueous solvents. The paper notes that spectroscopic techniques can be very useful in the elucidation of the structure of electrolyte solutions. Both the vibrational spectroscopy and particularly the alkali metal n.m.r. are very sensitive probes of the immediate chemical environment of ions in solutions. Another paper points out that the energy change associated with the solvation of ions can be represented as the sum of two energy terms; firstly, from the dielectric polarization of the solvent molecules in the continuous dielectric medium; and secondly, due to specific ion-solvent interactions in the inner solvation shells of the ions. The energy contribution of the latter is minimal but can show comparatively large differences in various types of solvents. Another paper describes the chemistry of solutions in highly associated strong protonic acid solvents, including sulphuric acid, oleums, fluorosulfuric acid, and hydrogen fluoride. Organic chemists, analytical chemists, investigators, and scientists whose works involve physical or inorganic chemistry will find the collection truly beneficial.

This paper also describes how IVRET can decrease the anisotropy of the angular distribution of photo dissociating molecules that takes longer than the rotational period of disassociation. The third paper explains rotations and electronic decay by focusing on nonresonant light scattering, which is explained in the theory of radiationless transitions, when the exciting light source is included.
