by means of this model and quantum-mechanical rate theory , we can reproduce a number of important features of the primary photosynthetic processes concerning in particular the temperature ( tunnelling or thermally activated nuclear motion ) and free energy dependence ( 'normal ' , 'activation-less ' , or 'inverted ' regions ) of the rate constants and estimate such parameters as nuclear-reorganization energy electron-exchange integrals and electron-transfer distances .
