Thermochemistry and Its Applications to Chemical and Biochemical Systems The Thermochemistry of Molecules, Ionic Species and Free Radicals in Relation to the Understanding of Chemical and Biochemical Systems - Ribeiro da Silva, Manuel A. V. (Springer Netherlands, 1984)
The progress that has recently been made in the field and applications of thermochemistry, having as a consequence an increase in the interest of the subject, undoubtedly can be considered highly remarkable. Traditionally, the thermochemist has provided accurate thermal data on chemicaZ compounds of practical importance, mainly by calorimetric and by equilibrium studies. The scope has been considerably extended in recent years, following the development of microcalorimetric techniques, of flow calorimetry, of titration calorimetry, and of high temperature calorimetry. The impact has been most noticeable in biochemical studies, in metallurgical studies, and in organometallic and inorganic thermochemistry. A parallel development has led to increasing output of significant thermal data on gas-phase transient species (e.g. free radicals, radical ions) by kineticists, and by use of photoionization spectroscopy, mass spectroscopy and ion-cyclotron resonance spectroscopy. These species are outside the scope of traditional calorimetric study, but as more data on them become available they vastly add to the value of traditional thermochemical data and enable bond energies to be evaluated, and the interelation of molecular structure and bonding energy to be more closely examined
