 I have Gaussian 03, and I have one question.
 How can I find the Bond dissociation energy (BDE) of a bond? is it done by
 isodesmic reaction or by
 simple calculation of the energy of products and starting materials and then
 just BDE=Products -
 Starting materials? is there a better approach? Can I apply this to covalent
 bond as well as a covalent-
 coordinate bond (like ligand-Metal type)? Anything should I be careful with?
 Thanks a million for the help
