  Article:   KEKULÉ COUNT IN TUC4C8(R) NANOTUBES.

Authors:  A. R. ASHRAFI, P. NIKZAD, A. BEHMARAM, H. YOUSEFI-AZARI.
 
       
         
  Abstract:  

Counting Kekulé structures is a very difficult problem in chemical graph theory. Some recent techniques allowed to estimate the lower bound of this number in certain classes of graphs. In this note a formula for the number of Kekulé structures in TUC4C8(R) nanotube is given.

Keywords: TUC4C8(R) nanotube, Kekulé structure.
