Benzaldehyde

For information on the vibrations of benzaldehyde go here.

 



This is the optimal geometry of benzaldehyde as calculated with the DZV basis set.

The DZV geometry optimization was chosen as the best geometry based upon comparison to reference data.


 



  Above is the HOMO for benzaldehyde.



 



The LUMO for benzaldehyde is shown above.



 



The electrostatic potential for benzaldehyde is shown here.
