  Article:   OMEGA POLYNOMIAL FOR NANOSTRUCTURES DESIGNED BY (P4)k Le OPERATIONS.

Authors:  MAHBOUBEH SAHELI, MIRCEA V. DIUDEA.
 
       
         
  Abstract:  

New cages are designed by repeating P4 map operation and finalized by Le operation. The energy of some small non-classical fullerenes, tessellated according to above sequences of map operations was evaluated at the level of semiempirical method PM3. The topology of the networks is described in terms of Omega counting polynomial. Close formulas for this polynomial and the Cluj-Ilmenau index derived from it, as well as formulas to calculate the net parameters, are given.

Keywords: Counting polynomial, CI index, non-classical fullerenes.
