Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibers. And they and their close relatives are produced by some glands such as the pituitary and the adrenal glands. In this study, the number of carbon atoms in fullerenes was used as discriptors to establish a good relationship between the structure of Epinephrine and Fullerenes Cn (n= 60, 70, 76, 82 and 86). The first to forth free activation energies of electron transfer and kinetic rate constant of the electrontransfer, ∆G# et(n) and ket(n), λet(n) n=1-4 , respectively were calculated in this study for Epinephrine with Fulleren Cn complexes with used calculated of four free energies of electrontransfer âˆ†G# et(n) (âˆ†G# et(4) to âˆ†G# et(4) of this supramolecular complexes. This calculation are agree with the Marcus theory.
