The Chemist's Companion

Here in one source is a wide variety of practical, everydayinformation often required by chemists but seldom found together,if at all, in the standard handbooks, data collections, manuals,and other usual sources. Discussing physical, chemical, andmechanical properties of substances and systems, the authors answersuch questions as:
* How do I test for and destroy peroxides in different solventsand what is the best way to purify such solvents?
* What are the structure, physical properties, and recentreferences to the use of common-name solvents and solvent aids suchas the "Skellysolves," "Cellosolves," "Crownanes," and"Glymes"?
* What is the utility of a particular molecular sieve, orpermeation gel, or epoxy cement, or liquid crystal, and where do Ibuy them and find references to their application?
The book is divided into nine chapters and covers properties ofatoms and molecules, spectroscopy, photochemistry, chromatography,kinetics and thermodynamics, various experimental techniques, andmathematical and numerical information, including the definitions,values, and usage rules of the newly adopted International Systemof Units (SI Units). A section on statistical treatment of datawhich provides an actual least-squares computer program is alsoincluded. In the spectroscopy chapter, very extensive andup-to-date collections of spectral correlation data are presentedfor ir, uv-vis, optical rotation, nmr, and mass spectra, along withdata on esr and nqr spectroscopy. Also included is a variety ofhard-to-classify but frequently sought information, such as namesand addresses of microanalysis companies and chemistry publishers,descriptions and commercial sources of atomic and molecular models,and safety data for hazardous chemicals. More than 500 keyreferences are also included, most of which are recent. There areimportant hints and definitions associated with the art as well asthe state of the art for the appropriate subjects. Also foundthroughout the book are about 250 suppliers and directions forobtaining special booklets or other material.

Containing a wealth of useful information, The Chemist'sCompanion will be an indispensable guide for students andprofessional chemists in nearly all the chemical disciplines. Inaddition, it will provide for the teacher and student an unusualadjunct for use in a broad cross-section of chemistry courses. Properties of Molecular Systems
