Goldschmidt model

Goldschmidt s mechanism was widely used by Hinshelwood240,2411 and Smith242 2431 for dilute solutions this corresponds to the experimental conditions for which relation (48) has been established. More recently, Van der Zeeuw244 applied Goldschmidt mechanism to the reaction of phthalic anhydride with model alcohols in concentrated solutions.

In this, the last major chapter of the book, we turn our attention to the applications of modern electronic structure models and eoncepts to more general geochemical problems namely, those described by Goldschmidt as being eoncerned with the distribution of elements in the geochemical spheres and the laws governing the distribution of the elements (see Preface).

Thus, in the case of solid solutions of sp Iqrbrid binary compoimds, Vegard s law applies to the average values of the bond lengths d, whereas d and d2 remain independent of the composition of the solid solution. The ideal lattice model with a random distribution of atoms over the sites is strictly applicable to solid solutions only if the values of d and d2 are similar, which implies that it is limited to solid solutions consisting of members of Goldschmidt s iso-electronic series, or members of groups of compounds classified in [9,10]. In all other cases, this approach is only very approximate. 

The review chapters in this volume were the basis for a short course on molecular modeling theory jointly sponsored by the Geochemical Society (GS) and the Mineralogical Society of America (MSA) May 18-20, 2001 in Roanoke, Virginia which was held prior to the 2001 Goldschmidt Conference in nearby Hot Springs, Virginia.
