Calculation of the mutual capacitance of nanoobjects

A method for determination of the mutual effective capacitance for molecules, molecular clusters, and nanoparticles on the basis of the quantum-mechanical calculation of the interaction energy of nanoscale charged objects is proposed. The mutual effective capacitance for pairs of similar molecules (carborane C 2 B 10 H 12 , fullerene C 60 , and molecular cluster Pt 5 (CO) 6 (PPh 3 ) 4 ) with a size of 0.3 to 0.7 nm is calculated for distances between these molecules from 2 to 20 nm. It is demonstrated that this method makes it possible to determine the scale of distances between nanoobjects for which it is necessary to take into account quantum corrections.
