Paperback for chemists and physicists

from Wikipedia, the free encyclopedia

The paperback for chemists and physicists is a three-volume table work. It was founded in 1943 by Jean D'Ans (1881–1969) and Ellen Lax and is therefore often referred to simply as D'Ans Lax . The fourth edition was published between 1983 and 2000.

Volumes

Volume 1 contains physico-chemical data
Spectroscopic data such as mass spectrometry , basic terms, X-ray spectra, AAS , NMR , Mössbauer spectroscopy , PE, UV / VIS , IR , ESR , fluorescence and microwave spectra , laser spectra, electronic structure of atoms , ions and molecules ( electrode potentials , Conductivity , ionic radii , atomic factors, core distances, valence angles), a list with all known nuclides and core particles , a periodic table , magnetic, electrical and optical constants, data on molecular mechanics and quantum statistics , dynamic constants ( viscosity , diffusion , thermal conductivity , reaction rates), physical- chemical data of water , interfaces , gas theory , measurement systems, metrological data, basic constants.
Volume 2 deals with organic substances
Data such as the exact name, (structural) formula, molar mass , density , melting and boiling point as well as other characteristics such as refractive index , solubility in various solvents , possibly taste and smell are given for approx. 10,000 organic compounds . Further tables list these compounds according to increasing melting and boiling points.
Volume 3 deals with inorganic substances and chemical elements
It contains caloric, mechanical-thermal and thermodynamic data on inorganic compounds, their formulas, solubilities, melting and, if applicable, boiling points. Such data of elements and many crystal structures of inorganic compounds are given.

Scope and price

In terms of size (and price) it lies between the chemists' calendar and the Landolt-Börnstein . The latter is only available in larger university libraries. The "D." can be found in many laboratories.
