The only thing that they did here was mathematically model the way that this interaction would occur.

So how is this guy saying this Chemical Bonding was never known to science? Is he just 1 upping someones original hypothesis by providing the mathematical model?

I do not know much of anything on the subject, I was a failure where Chemistry was concerned.

This scientist is the first to computationally formulate a hypothetical model for what is going on in these bonding systems. Just because the computations work does not in any way imply it accurately depicts what is going on in the bonding system.

Effectively, he was the first to formulate a reasonable model for what is going on. No info on accuracy etc.

It's a little hard to verify this form of bonding in real life, though. The magnetic fields required are apparently orders of magnitude higher than what we can generate. Oh well......published in Science nonetheless, good for them!
Ummm....

I would be extremely doubtful that they were able to accurately model this system without boat loads of empirical evidence to go off of.
I also don't think this would qualify as a new intermolecular force. The external conditions are giving rise to anomalous molecular behavior due to the extensive increase in magnetic field, temperature, gravity etc.
Very interesting research, but really in its infancy.

In chemical terms, though, these types of reactions are extremely complex compared to those involved in general polymerization. You are right about it not being a new force, though. All intermolecular forces are essentially the same thing, just being applied differently.

That being said, this model will likely do more for astronomy than chemistry. Still really cool though.
