Association constants of α-cyclodextrin with phenols
I have an exercise that asks me to reason the why for the association constants of a α-cyclodextrin with the guest.
The higher the K the higher the stability of the complex, but I don't quite ...

How to find the global minima of a supramolecular complex in computational chemistry?
So this is more of a complex problem, and my masters thesis could greatly benefit if I find an answer to this.
Essentially, I have a supramolecular inclusion complex. There is this molecule A (the ...
