The Wiener index [86] can be expressed in terms of the distance matrix [87] and equals the half-sum of all distance matrix entries. Randi(5 [88] and Kier and Hall indices of order 0-3 [89] are calculated from coordination numbers of atoms or from values of atomic connectivity. The Kier shape index (order 1-3) [90] depends on the number of skeletal atoms, molecular branching, and the ratio of the atomic radius and the radius of the carbon atom in the sp hybridization state. The Kier flexibility index [90] is derived from the Kier shape index. The Balaban index depends on the row sums of the entries of the distance matrix and the cyclomatic number [92,93]. The information content index and its derivatives (order 0-2) are based on the Shannon information theory [95]. Modifications of the information content index are structural information content, complementary information content, and bond information content [96],... 

Table 1 constitutes a starting point for the choice of those analytical techniques that will provide the information required for re.scarch. development or problem solving. Rigid separation between structural/chemical and compositional information is not intended to be inferred from the list. There are many techniques that provide information in both categories (e.g., SAM. ISS the latter is also called LEIS), The separate sections on minerals, ceramics and glasses will illustrate the application of the techniques and their complementary information content.
