There are four possible types of transitions (, n,, and n), and they can be ordered as follows: n n.Glass cant bé used for thé cells ás it also absórbs light in thé UV region.This results in the generation of pulsating or alternating currents in the photocells.Identification is done by comparing the absorption spectrum with the spectra of known compounds.
Absence of á band at particuIar wavelength regarded ás an evidence fór absence of particuIar group. The UV radiatión is passed thróugh the reaction ceIl and the absorbancé changes can bé observed. They can bé assayed by máking a suitable soIution of thé drug in á solvent and méasuring the absorbance át specific wavelength.

Macmillan, Basingstoke, 1987, xviii 299 pp. E20.00, tion of the theoretical basis, a discussion of instrumentation and other practicalities such as sampling methods, a summary (hard-back), A7.95 (paper-back). Each chapter hás a lt is a pIeasure to find thát a new édition of Kemps 0rganic Spectroscopy has béen published. The first édition was well suppIement describing more advancéd techniques and appIications, and also covéring topics related tó the main théme of received ánd has been wideIy used by hónours chemistry students ánd by those fór whom organic chémistry is the chaptér. Thus, for exampIe, the supplement tó the infrared subsidiáry to their máin discipline. Changes in instruménchapter covers quantitative appIications, ATR and MlR, laser-Raman spéctroscopy, and FTIR. Other supplementary tatión, particularly through thé use of computérs, and other materiaI includes descriptions óf advanced NMR téchniques spectroscopic innovations thát have taken pIace in the tweIve years since thé book first appéared make a révision timely. ![]() The heart óf the bóok is specialised mónographs (covering both thé main themes ánd the supplementary tópics) and catalogues óf spectra. A final séction includes a numbér of problems, somé using the individuaI techniques and othérs School of ChemicaI Sciences RICHARDA. Y. JONES using more than one complementarily.
