So far, Eq. (103) is general and free from any approximation. To determine B (r), it is necessary to integrate Eq. (103) over the charging parameter X and to make some assumptions with respect to the X dependence of the correlation functions. The usual rules are the linear dependence of the correlation functions on X and the unique functionality of the bridge function already mentioned. But, in that case, there is some arbitrariness on it and, as pointed out by Lee [72], a quadratic dependence could equally well be assumed. In a rigorous way, a X dependent correlation function, say T(r, X), has to express as P X)T(r), with the conditions P(X) > P(X = 0) = 0 and P(X) < P(X = 1) = 1. Unfortunately, P(X) remains unknown whatever the correlation function under consideration. So, the way a test particle does couple with the rest of the fluid is an open question. The author has assumed that P(X) = Xn, namely h(r, X) = Xnh(r) and c(r, X) = Xnc r), which corresponds to an extention of the Kjellander-Sarman... 

Although the basic chemical features of coal can be qualitatively and in some instances semiquantitatively specified, average-structure models that purportedly reflect statistically preferred molecular structures of coal offer little that advances an understanding of coal. In part, this is due to a continuing paucity of relevant or reliable data and to the procedures used to formulate the constructs. But meaningful representations of molecular structure are currently also precluded by indications that the assumption that underlies average-structure models, namely, that there exists a more or less unique, systematic, rank-dependent, molecular chemistry of coal, is not sustained by the current evidence. Several examples, all drawn from the open literature, are presented to support the view that the chemistry of a coal is heavily influenced by its source materials and early formative history and that coals of similar rank may therefore be chemically much more diverse than is usually supposed.

Near edge X-ray absorption fine structure, NEXAFS, is able to provide information about the molecular orientation of molecules at surfaces. This potential depends on a unique feature of synchrotron radiation, namely that the polarization of the light with respect to the surface plane can be controlled. For the case of benzene on Pt( 111) which was first discussed in Section 4, we describe the NEXAFS selection rules for a molecule which is assumed to be adsorbed planar and parallel to the surface these reasonable assumptions are accepted by a large number of workers. For this case, excitations from a C(ls) into an unoccupied tt level are forbidden if the electric field of the incident radiation is parallel to the plane of the molecule. This is the case when the synchrotron radiation is incident normal to the surface, described as s-polarized light, and the selection rule leads to an intensity Is = 0. On the other hand, when the electric field is polarized normal to the surface, p-polarized light, as is the case when synchrotron radiation is parallel or at grazing incidence to the surface, the intensity.
