Reduction to the equations of Kassel and Eyring

To consolidate the discussion, it is instructive at this stage to reduce 

If the reactant molecule comprises s classical oscillators, the density of 

Further, eqn. (8) may easily be integrated over a Boltzmann distribution to recover Eyring s equation [7] (still neglecting total rotation). It was shown earlier that 

Now f hanging the order of summation and integration, adjusting the limits accordingly (following Marcus [5]) 

These comments complete the discussion of the basic equations of the Marcus- Rice theory and also link them to other familiar concepts. 

To consolidate the discussion, it is instructive at this stage to reduce the general equation, eqn. (8), to the particular case of a set of coupled, classical, harmonic oscillators, i.e. Kassel s model [3]. 

If the reactant molecule comprises s classical oscillators, the density of vibrational states is s-1/(s l) n(/i (). The complex constitutes s — 1
