In this case, the microscopic rate constant k(i,j --+ l,m;T) should be averaged over 26 Theory of elementary reactions the quantum states of the reactants. With this purpose, the population of various quantum states of reactants A and B should be known. Let [A(i)] = fg(i)[A] and [B(j)] = fa(j)[B] where fA(i) and fB(j) are the distribution functions of molecules A and B over quantum states i and j, respectively; [A] and [B] are the overall concentrations of A and B. 23) t,j (c) A(nl) + B(n2) ~ C(n3) + D(n4) (where nl, n2, n3, and n4 are the quantum numbers characterizing the vibrational states of molecules of reactants A, B and products C, D).
In this sample, neither the quantum states of reactants nor the quantum states of products are specified. We will call this process the elementary reactions and its rate constant will be named the rate constant. , the velocity distribution is the Maxwell-type and the state distribution is the Boltzmann-type, the equilibrium rate constant is obtained. The term "equilibrium" indicates that the different forms of energy (rotational, vibrational, electronic) are characterized by one temperature T (energy equilibrium).
Only when they are brought together at sufficiently short distances, the molecular interaction becomes so substantial that can lead to this or other detected result: charge transfer, excitation energy transfer, chemical reaction, etc. The minimum result of the interaction is the distortion of the trajectory of a moving particle, that is, a change in the motion direction. If some, at least minimum indicated result of the interaction of two particles A and B is observed during their motion, we say that the collision (scattering) occurred.
