CCL: covalency and ionicity



Dear Abhishek,

     You can use any energy decomposition analysis and you will obtain indirectly the covalency and ionicity of a bond. A direct determination is made
by using the natural bond orders, implemented in NBO 5.0.

                    Best regards,

                                    Sergio

Hello Abhishek,
 
I think population analysis (rather than energy decomposition) will give some idea about covalency against ionicity.
Desides this, the strength of covalent bond may also be judged by measuring density at the bond critical point.
 
Good luck,

Subject: CCL: covalency and ionicity

Dear All,

      Is there any computational method to calculate covalency of a particular bond ? In many article, It has been seen that this particular bond have some percentage of covalency and ionicity as well. Will energy decomposition method be helpful here ? What else a bond contains besides covalency and ionicity ? Please give your suggestion considering weak interaction along with covalent bond. Thanks a lot.

  Wish you a Merry Christmas and may this festival bring abundant joy and happiness in your life!
