This book covers quite well the applications of thermodynamic? to inorganic chemistry, especially as applied to ionic systems, and it could be a useful text for
part of the second semester of a senior inorganic course. Alternatively it could be used in a "chemical bond" course to st~pplement one of the standard texts since the latter tend to emphasize covalent subst,ances. Only t,he final chapter in this text is much concerned with covalent bonded compounds. The first chapter briefly reviews thermw dynamic and kinetic terms. The second chapter, The Ionic Model, develops such topics as ionic c r y ~ t a lstructures, lattice energies, ionic radii, and thermoehemical m i . The treatment of crystal strnctnres and Madelung constants is limited and would need to be supplemented by the use of some of the reference material. In Chapter 3, The Alkali Metals and the Alkaline Earths, the thermodynamic arguments which were developed in Chapter 2 are utilized in an interesting fashion to discuss heats of formation, decomposition t,emperatraes, and the types of deeomposition products predicted on the bases of ion sizes and charges. There are no problem sets a t the end of each chapter, unfortunately; study problems for assignment to the students would have been especially useful with this chapter. The topics considered in Chapter 4, Solution Equilibria and Electrode Potentials, include enthalpies, entropies, and free energies of aqnated ions; electrode potentials; equilibrium constants; relsi tive stabilities of oxidation states; solvent reactions; and non-aqueous solvents. The latter topic is described only briefly. The ideas involved in this chapter could be treated more extensively by the instruc-
t,or with referral t o "Oxidation Potentialsls" by W. M. Latimer, 2nd Ed., Prentice-Hall (l9R2), which also contains some good stndy problems on these subjects. I n Chapter 5, The Solubility of Ionic Salts, t,he various energy berms involved in t h e free energy of solution are discussed and related t o variations in the solubility prodncts with position of the ions in t h e periodic chart, i.e., wibh ion sizes and charges. The concept of hydrate formation leads into the development of coordination chemistry in Chapter 6, Transition Metal Chemistry and llelat,ed Topics. The related topics are ligand field theory, which is considered very briefly; stability constants of complexes; erect of coordination on electrode potentials; and &abilities of various oxidsliorr states of transition metals, lauthsnides and actinides. Bond Energies and Some Aspects of Non-metd Chemistry is t,he title of Chapter 7, and in this chapter the emphaqis is primarily an covalent, molecular compormds and some tvends in their bond energies. The P ~ o I i n gelectronegativky scale is ntiliaed in the consideration of h a r d energies. In a limit,ed number of pages sumo very int,eresting examples are diacnsscd in enough detail t o acquaint the stltdent with the factors that may infloence t,heenergot,ics of covalent bands. This hook in 1!16 pages af text material contains a qrdto concise discorsion of the energet,ic aspects of inorganic chemistry. Throughont the text and in the Appendices there are many helpful inhles of data. An itlieresting and usehd onesemester course could be developed a t the senior level hy using this hook eo,lpled with a n analog~ustl.eatment of kinetic, reartianmechmirm topics.
states in t h e preface, t,he book deals mainly with liqtrid solutions, but some reference is made t o solids, gases, and crystals. The mathematical treatment is essentially t h a t of simple algebra and a detailed knowledge of quantum mechanics is not necessary for mderstanding or reading the book. The book is divided into five major s~rbseetians: (1) Basic Principles and Ilefinitians, (2) Kinetics of Photolnminescence, (3) Apparatus and Experimental Methods, (4) Special Topics and Applications, and ( 5 ) Application t o Analytical Chemistry. Under Basic Principles and I)efinitions, the anthor treats a number of phenomena such as basic theory of fl~meseenceand phosphorescence, radiationless processes, delayed luminescence, polarization of luminescence, and light scattering phenomena. Under Kinetics of Photolomineseeure is a, discussion of tmnsition rates, fl~~orescence lifetime and efficiency, kinet,icr of phosphorescence, and kinetics of delayed solntion fluorescencc. The most extensive chapter, 3, Appnrntus and Experimental Methods, covers sueh topics ns monochromelers, light sources, filt.ers, detectors, amplifiel.~, geometrical factors affectingfluorescence measilremonts, spectral eorrertion, measnrement of quanium efficiency and measurement of polariaittion. Chapber 4, Special Topics and applications, covers sueh things as d e t e c minatian of parameters of singlet and triplet states, excited state equilibria, excimers, solvent effects, and the use of phatol~tminescence in the study of irre-
In versible photochemical reactions. chapter 5, Applications to Analytical Chemistry, such topics are covered as definition af sensitivity, factors contributing t o the luminescence blank, structural relationships between luminescence and organic compounds, and analyses of both inorganic and organic substances. I n the opinion of this reviewer, Parker has prod~lceda book which is both comprehensive and readable. Although his treatment of theory relating to luminescence processes is quite complete, he treats it a t a level that it could be readily understood by an advanced undergraduate or graduate student having only minimal acquaintance with quantum mechanics. The section on apparatus and experimental methods as well as definitions such a s analytical sensitivity should be of great utility t o workers in a wide variety of areas. I n many respects, the chapter on apparatus and experimental methods is a self contained course in optical instromentation, as i t relates t o construction of s ~ e c t r o ~ h o t o m e t e rand s s~ectrofloorometers. I n general, the format of the hook is pleasing and relatively few typographical errors are noted. About the only adverse criticism of the book that this reviewer would care to offer relates t o the price. I t seems very unlikely that each laborstory chemist dealing with luminescenee will acquire his own personal copy. D W I D hf.
