Title: Is Bondon Theory required to explain chemical bonding?
Post by: NeilT on 01/09/2019 19:29:27
This is proposed by Mihai Putz and seems to involve a transient particle (a bondon). It's mentioned in the book Structural Chemistry by Putz, Cimpoesu and Ferbinteanu.

 As he's proposing a bondon to be a massive particle, wouldn't it have shown up by now in an accelerator somewhere? And is there a full understanding of the quantum process involved in making and breaking chemical bonds?

As far as I understand, all of chemical bonding can be described using photons (as quanta of the EM field, which mediates the interactions of electrons and nuclei.)

Accelerators focus on electrically charged, high-energy individual particles.
- We are talking energies in MeV or GeV

Stable atomic bonds are formed in a complex structure involving many atoms (often billions), which is (overall) electrically neutral.
- We are talking energies in eV per bond

So a particle accelerator would blow apart a bondon, even if it were able to create one.

A similar situation occurs for the Cooper pairs involved in some forms of superconductivity, which involves the interaction of phonons (billions of atoms) with electrons. The energy here is of the order of 10-3 eV per bond.
