Shason Shaik and collaborators have a nice article in the latest Nature Chemistry, "charge-shift" bonding which is the essential component of the bonding of pairs of very electronegative identical atoms (e.g., flourine).
The essential physics of covalent bonding can be described by a two-site Hubbard model (with U>>t).
Can a negative U (or V>U) two-site Hubbard model describe the essential physics of charge-shift bonding?
