An invaluable source of information: 1175 critically selected and evaluated UV-VIS spectra of organic and inorganic compounds. Handy features include: * transmission curves for the most important spectroscopic solvents * 177 tables showing the effects of substituents and solvents on typical chromophores * helpful indexes (unsaturation values, substance names and classes, molecular formulas, CAS Registry Numbers ...) * supplementary texts on individual substance classes by renowned experts This critical, comprehensive yet compact collection of absorption spectra will be of lasting value to both the specialist and non-specialist. Heinz-Helmut Perkampus is an established authority in ultraviolet and visible spectroscopy. A Professor of Physical Chemistry at the University of D?sseldorf for over 20 years, he has published prolifically in the field.
