The dependence on the nuclear positions is indicated by r and the dependence on the Drude positions is indicated by d. In Eq. (9-25) Ubond (r) is the intramolecular energy contribution from, typically, the bond lengths, valence angles, and dihedral angles, Ulj (r) is a Lennard-Jones 6-12 nonpolar contribution, Ueiect (r, d) represents all Coulombic interactions, atom-atom, atom-Drude, and Drude-Drude, and Useif (d) represents the atom-Drude harmonic bonds. The term Usey (d) arises from the harmonic spring separating the two charges and has the simple expression... 

The dipole-inducing mechanims of simple binary systems, such as atom-atom, atom-diatom, and diatom-diatom complexes with limited numbers of electrons, are well understood. For example, the exchange force-induced and dispersion-force-induced dipole components have been accurately computed for several simple systems, using quantum chemical methods (Chapter 4). The classical multipolar induction scheme is well known since the discovery of interaction-... 

Morse curve with the coefficients depending on two angular variables one (a) defines the deviation of the molecule from linearity, while the other (v) defines the angle of rotation of the Morse potential around a fixed point on the atom-atom-atom dissociation plateau (Ru is the distance between this point and the minimum of the Morse curve) ... 

Expansion at long range gives rise to the typical R n dependence of the intermolecular interactions. The first components of the long-range intermolecular interaction were studied by the author and coworkers in two papers (Magnasco et al., 1988,1990b), where the first few coefficients of the R expansion were determined explicitly for atom-atom, atom-linear molecule, and linear molecule-linear molecule systems.

Somewhat similar to enzyme kinetics, but definitely not the same, is the area of microbial kinetics. Here one is concerned with reactions between entities that may not be of the same level of organization (i.e., not atom-atom, atom-molecule, etc,). Indeed, microbial kinetics is more concerned with interactions between populations of living organisms, and some of the problems seem more akin to population dynamics than to chemical kinetics. In fact, in much of the discussion below we are concerned with population-changing processes. First, we need to define a few terms.
